Steam traps
The main purpose of the steam trap is to hold perfectly steam and discharge the condensate quickly and
fully.
In addition to these essential features, the steam trap must also discharge air and non-condensable
gases. All our steam traps completely satisfy these requirements.
Our products range include different models having technical characteristics suitable to meet every kind of
requirements or applications.
In this page the main steam traps are indicated by family sorted by technical and operating
characteristics, as well as the condensate commander pumps and the steam separators.

The selection of steam traps for specific applications is made in two steps:
A. Choice of type
B. Choice of size
Before discussing these steps, it is necessary to make a general comment from the economic point of
view.
Giving as granted that the condensate must be discharged, it is highly important not to loos live steam in
this process. Assuming that today’s cost of steam is approximately 0,02 Euro to a kilogram (and this is
very conservative), it follows that a trap, sized for 200 kg/h losing 10% of its steam, in a refinery onstream
24 hours/day, costs in one year 146,00 Euro.
If this refinery has 1.000 steam traps incorrectly sized and, therefore, in such conditions, the loss will be
146.000,00 Euro per year!
One can easily calculate what happens if the trap has failed in the open position instead of just losing
some steam. The choice of the type and size to a steam trap is a matter of great importance.
A. Choice of type
The main criteria for the selection of the type are (they cannot be listed in order of importance since it
varies from application to application):
- Resistance to freezing
- Installation versatility
- Air venting
- Resistance to water hammer
- Type of discharge (with temperature regulating control valves, the modulating type is preferable)
- Heat Exchange efficiency (traps discharging sub cooled condensate do not allow an efficient heat
exchange)
- Sensitive to back pressure
- Reaction to load changes
- Pressure variations (types requiring changes of orifices for different pressure are unfit for wide
variations)
- Dimension and weight
B. Choice of size
There are 3 parameters to take into account for a correct sizing:
1. Differential pressure
2. Condensate load to be discharged
3. Safety factor
1 – Differential pressure
The differential pressure is simply the difference between the pressure upstream and downstream of the
trap. When a trap discharges at the atmosphere, the downstream pressure is zero (we always refer to
relative and not absolute pressure) and the differential pressure is the same of the line. When there is a
condensate return system, there is always some pressure inside it due to friction and line lifting. The best
way to know the value of downstream pressure (also called backpressure) is to install a pressure gauge
just after the trap. If this is not practical, one should calculate the amount of backpressure by formulas of
pressure drop in water ducts adding approx. 0,1 bar for each meter of rise.
2 – Condensate load
This is the second parameter to be introduced into the capacity tables. For draining of steam mains the
quantity of condensate is related to the size of the pipe, to the stream pressure, to the efficiency of
thermal insulation, to the outside temperature, to the wind force if any and to the temperature of the line
(cold start-up or running conditions). In all the other applications traps are used to drains machines
utilizing steam as a heating medium. In these cases the quantity of condensate to be removed will be
equal to the amount of steam used by the machines to give the desired performance.
3 – Safety factor
For many reasons the steam trap will not be able to handle on field the condensate loads given in the
capacity tables. These reasons are:
- Type of discharge (intermittent or continuous)
- How the condensate reaches the trap
- Presence of large quantities of air
- Influence of other traps discharging in the same return line
Moreover, there may be incorrect assumptions in the condensate load calculation and it is necessary to
take into account at a cold start-up the quantity of condensate to be discharged is a lot more than at
running conditions. To summarize, the size of the trap is selected entering the capacity tables with the
differential pressure and with the condensate load multiplied by the safety factor. A minimum safety factor
1,2 or 1,5 must be always taken into consideration. Higher safety factors (2 or 4) are required for certain
applications.
Installation
Specific suggestions for a correct installation depend on the application and on the type of selected trap.
The following are some general comments:
- The trap should always be installed below the drain point.
- Try to avoid condensate lifting. If this is necessary, install a check valve just after the trap.
- Always install “Y” type strainer upstream, unless the trap has a built in “Y” type strainer.
- Mechanical and thermodynamic traps should be installed as close as possible to the drain point.
- Thermostatic traps should be installed at 1 or 2 mt. from drain point. Do not insulate this cooling leg.
- It is advisable to install a check valve upstream of an inverted bucket trap to prevent water seal loss.
- A sight glass fitted downstream the trap allows a continuous check of the trap operation.
- Always install isolating valves upstream and downstream for maintenance purposes.

OPERATION
Thermal actuator is filled at its free length with a liquid having a lower boiling point than water. On start-up,
valve is normally open. When steam enters trap, thermal actuator fill vaporizes to a pressure higher than line
pressure. This forces valve into seat orifice to prevent any further flow. As condensate collects, it takes heat
from thermal actuator, lowering internal pressure. Line pressure will then compress thermal actuator to open
valve and discharge condensate. Valve opening automatically adjusts to load conditions from minimum on
very light loads to full lift at maximum load. Restricted orifice in N125L (small opening at bottom of valve seat)
prevents trap from discharging continuously on light loads.

The thermostat element is filled with a liquid having a lower boiling point than water.
As assembled, the steam trap is normally open, allowing discharge of air, non-condensable gases and
condensate. When steam enters the trap, the liquid inside the thermostat element vaporizes, forcing valve into
seat orifice avoiding discharge of steam. As condensate enters the trap, the bellow compress allowing its
discharge.
The construction of the thermostat element is suitable to satisfy, with extreme precision, both low and high
flow rate..

OPERATION
Thermal actuator is filled at its free length with a liquid having a lower boiling point than water. On start-up,
valve is normally open to discharge air, non-condensibles and condensate. When steam enters trap,
thermal actuator fill vaporizes to a pressure higher than line pressure. This forces valve into seat orifice to
prevent any further flow. As condensate collects, it takes heat from the actuator, lowering internal pressure.
Line pressure will then compress thermal actuator to open valve and discharge condensate. Valve opening
automatically adjusts to load conditions from minimum on very light lo0ads to full lift at maximum load.

OPERATION
Incoming air and condensate flow through the trap body and into the control chamber. Line pressure raises
the disc off the seat allowing complete discharge. When flashing condensate enters the cartridge, flow velocity
increases, creating low pressure underneath the disc.
Flashing condensate at high velocity strikes the inside wall of the disc chamber and is deflected to the top of
the disc causing a pressure buildup. The disc is forced down onto the seat by this pressure imbalance. The
trap remains closed as flashed vapour in the control chamber keeps the disc seated. Pressure inside the cap
is not lowered until the trapped flash vapour condenses due to body radiation. Condensing steam lowers the
pressure above the disc. Disc is then lifted and the cycle repeated.

OPERATION
Thermodynamic steam trap mod. DTF.2P is disc type with 2 pieces construction, body completely in stainless
steel, possibility of BW connections in carbon steel for a perfect weldability, very good resistance to high
pressures, can be installed in every position.
Thermodynamic steam trap is easily monitored because discharge is audible to ear.
Its mechanical characteristics allows the steam trap to be used at high pressures and tough conditions, even
with superheated steam. It has a very good resistance to freezing because it’s self-draining.
To select and size a steam trap, the following factors must be taken into consideration:
x Maximum operating pressure and maximum differential pressure, back pressure, condensate lift height,
etc.
x Maximum quantity of condensate to be discharged under normal operating conditions.
x Safety factor for the flow capacity (considering the critical start up phase): 1,5-2 with continuous flow, 2-2,5
with non continuous flow.

OPERATION
On start-up, the thermostatic air vent (caged stainless welded bellows) is open, allowing air to flow freely
through the vent valve orifice. When condensate flows into the trap, the float rises, allowing condensate to be
discharged. Once air and non-condensibles have been evacuated, hot condensate will cause the thermostatic
vent to close. Condensate will continue to be discharged as long as condensation occurs.
During normal operation, an increase in the load causes the liquid level in the trap to rise. The float then rises
and rolls off the seat ring, allowing more condensate to flow out. The float sinks as the condensate load
decreases, moving nearer to the seat ring, decreasing the effective size of the orifice and allowing less
condensate to discharge. This provides smooth, continuous operation that reacts instantly to load variation
while maintaining a water sea over the seat ring to prevent live steam loss.

OPERATION
On start-up, the thermostatic air vent (caged stainless welded bellows) is open, allowing air to flow freely
through the vent valve orifice. When condensate flows into the trap, the float rises, allowing condensate to be
discharged. Once air and non-condensibles have been evacuated, hot condensate will cause the thermostatic
vent to close. Condensate will continue to be discharged as long as condensation occurs.
During normal operation, an increase in the load causes the liquid level in the trap to rise. The float then rises
and rolls off the seat ring, allowing more condensate to flow out. The float sinks as the condensate load
decreases, moving nearer to the seat ring, decreasing the effective size of the orifice and allowing less
condensate to discharge. This provides smooth, continuous operation that reacts instantly to load variation
while maintaining a water sea over the seat ring to prevent live steam loss.

OPERATION
Air entering trap is immediately discharged through the high capacity integral air vent. The thermostatic vent
will close just prior to saturation temperature. The balanced design will allow venting of non-condensibles that
collect in the float chamber when operating at design pressure. When steam enters the trap, the thermostatic
air vent closes to prevent steam loss. When steam gives up it’s latent heat, it becomes condensate. This
“condensate” enters the trap and causes the stainless steel ball float to rise. Raising of the float opens the
discharge valve, allowing condensate to be continuously discharged as it enters the trap. The condensate
level in the trap body is maintained above the discharge seat, providing a positive seal against the loss of
steam.

OPERATION
During startup, air and non-condensible gases enter the trap and are automatically vented through an
accurate balanced pressure internal thermostatic air vent. As condensate enters the trap, the float and lever
mechanism is raised, lifting the valve off the seal, discharging the condensate. Condensate will continue to be
discharged at the same rate at which it is entering. Any air or non-condensible gas that may accumulate will
be continually and efficiently passed by the thermostatic air vent.

OPERATION
Trap closed
After trap is installed and
primed, steam entering the
trap collects in the top of he
bucket, floating the bucket
and forcing the valve into its
seat.
Trap begins to open
As condensate begins to
flow into the trap, steam and
air are forced from the
bucket. This causes the
bucket to begin losing
buoyancy, tending to pull the
valve from its seat.
Trap discharges
When enough condensate has
entered the trap, displacing
the steam and air, the bucket
drops, polling the valve from
the
seat
and
allowing
condensate
and
air
to
discharge.
Trap closes
As the flow of condensate
stops, steam enters the trap
and refloats the bucket,
forcing the valve into its seat.
The cycle then repeats as
more condensate reaches
the trap.

OPERATION
Trap closed
After trap is installed and
primed, steam entering the
trap collects in the top of the
bucket, floating the bucket
and forcing the valve into its
seat.
Trap begins to open
As condensate begins to flow
into the trap, steam and air
are forced from the bucket.
This causes the bucket to
begin
losing
buoyancy,
tending to pull the valve from
its seat.
Trap descharges
When enough condensate has
entered the trap, displacing the
steam and air, the bucket
drops, polling the valve from
the
seat
and
allowing
condensate
and
air
to
discharge.
Trap closes
As the flow of condensate
stops, steam enters the trap
and refloats the bucket,
forcing the valve into its seat.
The cycle then repeats as
more condensate reaches
the trap.

x
Always install a steam trap after the steam separator.
Always install a Y strainer between the steam
separator and the steam trap.
OPTIONS
x
Optional insulation jacket
OPERATION
When the steam enters the separator, a series of baffles change its flow direction several times. During this
process, the baffles in the housing collect impinged water droplets that are carried in the system. Gravity
allows the accumulated water droplets and other foreign particles to fall to the drain and exit the system
through a steam trap. The remaining steam in the system is clean and dry, allowing improved and maintained
performance.

OPERATION
The vent valve is open, the pressure supply valve is closed and the float is positioned in the lower part of the
tank as the condensate or other liquid enters the tank through the inlet check valve. As the tank fills with liquid,
the float rises to the point where the spring mechanism snaps past the center position. The compressed
spring instantly closes the vent valve and opens the pressure supply. This allows pressure into the tank which
forces the liquid through the outlet check valve.
As the liquid level falls, the float lowers to the point where the spring mechanism snaps past the center
position which immediately closes the pressure supply valve and opens the vent valve. The pressure in the
tank decreases, allowing liquid to flow through the inlet check valve, repeating the cycle.

SIZING
The sizing is done by determining the necessary Kv. The Kv is the quantity in m3 of water at 15°C that passes in one hour
through the valve with differential pressure DP 1 bar.
The formulas below allow to determine the coefficient Kv required taking into account the fluid and operating conditions.
The selected DN will be the one that offers a Kv higher than the calculated one.

OPERATION
D50SS pressure reducing valve is self operated, requiring no external energy source. It is usually used for
clean steam and sterilization applications.
Regulator is actuated by changes in the downstream pressure. Any increase in the downstream pressure
above the set point (due to decreased fluid demand) will force the diaphragm up and overcome the resistance
of the spring, allowing the valve to close. Any decrease in the downstream pressure (due to an increase fluid
demand) will decrease the pressure on the diaphragm and permit the spring to open the valve.
Pressure reducing valve mod. D50SS can be adjusted by acting on the upper bolt.

SIZING
The sizing is done by determining the necessary Kv. The Kv is the quantity in m3 of water at 15°C that passes in one hour
through the valve with differential pressure DP 1 bar.
The formulas below allow to determine the coefficient Kv required taking into account the fluid and operating conditions.
The selected DN will be the one that offers a Kv higher than the calculated one.

OPERATION
The pressure reducing valve mod. VP is self-operating, proportional action with internal pilot. This valve allows
to keep the downstream pressure constant at upstream pressure changes. The valve is normally closed and
the set pressure can be adjusted acting on the calibration screw.
The upstream water pressure reaches the valve, presses the piston and automatically the balance of the
upper chamber is obtained. Once the valve closes, the set point is achieved by turning the adjustment screw
clockwise. This produces a compression of the spring that automatically repositions the piston and the plat by
opening the valve just enough to reach the required value. Any variation of the upstream pressure will be
absorbed by the valve through the offset between the piston and the balancing chamber.

OPERATION
The pressure reducing valve mod. PRV45 is self-operated direct action with internal pilot. This valve allow to
keep the constant the downstream pressure to upstream pressure changes.
When the pressure enters the valve, closes it because of the sections difference. When the spring is
compressed through the regulating screw, all stem-seal open the valve and allow the regulation.
When any downstream valve is closed and flow=0, the pressure reducing valve will absorb oscillations and
maintain outlet pressure according to regulation. The valve closes when the downstream pressure exceeds
the regulating set pressure.
To increase outlet pressure, the regulating screw should be turned clockwise.

OPERATION
The pressure reducing valve mod. M2 is self-operated with internal pilot. This valve allows to keep constant
the downstream pressure to upstream pressure changes.
When fluid enters the valve, it acts on the plug closing the valve. In order to adjust the downstream pressure it
is necessary to act on the adjusting screw clockwise. This causes the moving of the spring, which will open
the plug until the required downstream pressure is reached.
Each upstream change will be absorbed by the valve stem, while the downstream pressure by the actuator’s
diaphragm.

OPERATION
The pressure reducing valve mod. M3 is self-operated with internal pilot. This valve allows to keep constant
the downstream pressure to upstream pressure changes.
When fluid enters the valve, it forces stem-piston-gasket to close the valve. In order to adjust the downstream
pressure it is necessary to act on the adjusting screw clockwise. This causes displacement of the spring,
which acts on the diaphragm closing the guide and support seals opening the valve until the required
downstream pressure is reached.
Any variation in the upstream pressure will be absorbed by the compensating piston, while the downstream
pressure by the diaphragm.

OPERATION
The pressure reducing valve mod. VM is self-operated with external pilot. This valve allows to keep the
downstream pressure constant at upstream pressure changes. The valve is normally closed and the set
pressure can be adjusted acting on the calibration screw.
Opening the interception valves, the fluid enters the reducing valve, push the plug up and move downstream.
Then, part of it is conveyed to the sensing line and moves to the diaphragm of the actuator.
At this point, the spring loading or unloading by means of the calibration nut, will adjust the value of the
required downstream pressure, thus achieving a proper balance between the constant pressure of the lower
chamber of the diaphragm and the spring.

OPERATION
The pressure excess valve mod. S2 is self-operated with direct action. When upstream fluid reaches the
valve, it acts on the plug opening the valve. This pressure is balanced by the stem which, in case of lack of
pressure, closes the valve using the regulation spring. When upstream pressure reaches the diaphragm
through the external line and rises upto the set pressure, the valve proportionally opens. In order to regulate
the valve, turn the regulation screw clockwise until the required upstream pressure is obtained.

OPERATION
The operation is similar to a safety valve, but with the advantage that
the pressure excess valve regulates the discharge of pressure in the
main pipe.
In picture 1 the valve is in rest position, no fluid running through it.
In picture 2, once the plant is saturated, the pressure of the main line
comes to the valve through the pressure tap and the valve
connection. It’s the moment to adjust the set pressure required for the
main line by the regulation screw.
In picture 3 the pressure excess valve is working, as the pressure tap
of the piping collects a signal higher than the calibration; the valve
then opens discharging in the secondary line.
When the primary line is back to normal calibration or less, the
pressure excess valve closes, waiting for a new rise in pressure.

Valvole rompivuoto / Vacuum breaker valves
VRV 1
Queste valvole sono state studiate per
evitare la formazione di vuoto negli
apparecchi ed impianti a vapore di
piccolo e medio volume, come
scambiatori, batterie ad aria calda,
serpentini, tubazioni di distribuzione,
ecc.
These valves are designed to avoid
the formation of vacuum in the
devices and steam systems of small
and medium volume, such as heat
exchangers, hot-air batteries, coils,
distribution pipes, etc.
Al primo accenno di formazione di
vuoto nell’apparecchio a causa della
condensazione del vapore, la valvola
si apre automaticamente ed immette
aria dall’ambiente fino a stabilire
all’interno dell’apparecchio la pressione atmosferica; richiude e rimane
chiusa con valori di pressione
superiori.
At the first sign of formation of
vacuum in the device due to the
condensation of steam, the valve
opens automatically and supplies air
from the environment up to establish
atmospheric pressure inside the
device; it closes and stays close with
values of higher pressures.
Può essere applicata sia subito a valle
del termoregolatore o delle valvole di
alimentazione vapore all’utenza, sia fra
l’utenza e lo scaricatore di condensa
(ovvero sulle sommità del corpo dello
scaricatore, se di tipo a galleggiante).
It can be installed either immediately
downstream
the
temperature
regulator or the valves for steam
power to the user, or between the
user and the steam trap (i.e. on the
top of the steam trap if a float type).

INSTALLATION
The flow indicator has, as its main function, the control of the smooth operation of the steam trap. For this
reason, its correct position is downstream the trap in order to verify its correct operation.
When the steam trap is the float & thermostatic type, it is recommended to place the indicator next to the trap,
having a modulating and non-violent drain, the glasses of the indicator does not suffer from erosion and make
more visible the flow. For other types of trap, such as inverted bucket, thermostatic and thermodynamic, it is
recommended to place it after about one meter.

Compensatori di dilatazione assiali / Axial expansion joint
I compensatori di dilatazione assiale agiscono in genere solo nella
direzione del proprio asse. Potendo assorbire dilatazioni sia a
compressione che a trazione, trovano applicazione specialmente in tratti
di tubo o collegamenti di apparecchiature, che siano perfettamente
rettilinei. Trovano uso sugli scambiatori di calore allo scopo di assorbire
le dilatazioni differenziali tra il mantello esterno e il fascio tubiero. Altro
impiego dei compensatori assiali si trova nelle tubazioni di aspirazione o
di scarico, dove i giunti servono per lo smorzamento, assiale o laterale,
di vibrazioni di frequenza non altissima.
Sono normalmente disponibili a stock nella versione con
compensazione di 30 mm con flange girevoli o bocchettoni BW. Quelle
con compensazioni di 60 mm, attacchi a flange fisse, bocchettoni filettati
maschio e/o femmina sono disponibili in tempi piuttosto brevi.
Axial expansion joints usually work along their own axial direction only.
They can support either compression or traction expansions, but they
are generally used between pipelines sections or to connect various
equipments provided that their operating performance take place along
an absolute rectilinear section only. Their operating performances are
necessary in the following circumstances: 1st) in heat exchanger
equipments in order to absorb differential expansions between outer
shell and tube bundle; 2nd) as "demounting joints" in order to facilitate
the assembling and disassembling of valves, gate valves and so on. In
fact thanks to their elasticity, during unscrewing of the bolts they leaves
a little clearance between flange and counterflange large enough to pull
the valve out. They are also used in intake and exhaust pipes in order to
attenuate moderate axial or lateral frequency vibrations.
These are usually available in stock with 30 mm of compensation and
floating flanges or BW ends. The ones with 60 mm of compensation,
fixed flanges, male or female treaded ends are available in a short time.

INSTALLAZIONE
Prima di montare la valvola, aprirla portando l’otturatore a circa metà dell’intera corsa. Accertarsi che l’interno del corpo
sia completamente pulito. Eventuali impurità dovranno essere rimosse per assicurare un corretto funzionamento, se si
dispone di aria compressa utilizzarla per una migliore pulizia.
Verificare che le flange ove sarà inserita abbiano i fori in asse, siano parallele e non vi sia troppo o poco spazio tra di
esse tenendo conto dello spessore delle guarnizioni impiegate, del loro naturale appiattimento dopo il serraggio dei
dadi nonché delle tolleranze sugli scartamenti indicate dalla norma EN 558-1.
La valvola deve essere montata secondo la direzione del flusso indicato dalla freccia rilevabile sul corpo. Fissare la
valvola nella corretta posizione della linea e ricordarsi di inserire le guarnizioni tra le flange centrandole il più possibile
sui risalti, i quali dovranno essere puliti per permettere la corretta tenuta.
Inserire i bulloni nei fori delle flange e serrarli mantenendo una frequenza diametralmente alternata (per una migliore
deformazione delle guarnizioni). Controllare il corretto funzionamento aprendo e richiudendo completamente la valvola
per due o tre volte.
INSTALLATION
Before assembling the valve at the pipeline, open it until about half-stroke. Check inside the body to be completely
clean, possible impurities have to be removed in order to ensure a right functioning. If compressed air is at your
disposal, use it for a better cleaning.
The counter-flanges of the pipeline must be parallel and have aligned holes. Check the space between them, keeping
into account the gaskets and their flattering after bolts closing (it should not be too much or too little) and face to face
tolerances as per EN 558-1 standard.
The valve must be assembled following the direction indicated by the arrow on the body. Fix the valve in the right
position at the pipeline and remember to insert the gaskets between the flanges centring them as much as possible on
the raised faces, which have to be clean to allow a correct tightness.
Fit the bolts in flanges holes and tighten them maintaining a diametrically opposed sequence (for a better deformation
of the gaskets). Check the right functioning of the valve with two or three complete open-close operations.

INSTALLAZIONE
Prima di montare la valvola, aprirla completamente. Accertarsi che l’interno del corpo e le parti filettate siano pulite.
Eventuali impurità dovranno essere rimosse per assicurare un corretto funzionamento, se si dispone di aria compressa
utilizzarla per una migliore pulizia.
Avvitare la valvola al tubo filettato usando una chiave proporzionata alla grandezza della stessa.
Per ottenere una corretta tenuta sui filetti utilizzare nastro di PTFE, canapa o altro prodotto compatibile al fluido in
quantità adeguata, poiché un eccessivo impiego potrebbe causare la rottura dei manicotti.
INSTALLATION
Before assembling the valve at the pipeline, open it completely. Check inside the body and the threaded parts to be
clean, possible impurities have to be removed in order to ensure a right functioning. If compressed air is at your
disposal, use it for a better cleaning.
Screw the valve at the threaded pipe using a suitable wrench.
In order to get a correct sealing on threadings it is useful to employ PTFE, hempen tape or other products compatible
with the fluid, in adequate quantity since an excessive employ could cause the couplings breakage.

INSTALLATION
This type of valve can be installed in any position. Only in the version WITHOUT spring should be installed
in vertical pipe with fluid ascending. Installation is simple because the valve is self-centering in the flanges.
In assembly the correct seal suitable for the type of fluid must be chosen.
The purpose of the valve is to preserve the equipment upstream from unwanted back pressure that could
damage the proper functioning.

INSTALLATION
Double plate check valve is a general purpose and one way flow valve that is stronger, lighter and more
reliable than conventional swing check valve. Due to restrained weight and short face-to-face dimension, it’s
very easy to be maintained and installed between flanges. The plates are supported by two semicircular
springs; the plates close by springs action and open by fluid pressure. Due to the very quick reaction of
springs cycle, the double plate check valve helps to protect the pipe from water hammers.

INSTALLAZIONE / INSTALLATION
La valvola deve essere montata secondo la direzione del flusso indicato dalla freccia rilevabile sul corpo.
L’unica perdita possibile è la mancata tenuta della sede, normalmente attribuibile all’usura nel tempo o a
possibili corpi estranei presenti nella tubazione.
The valve must be installed following the flow direction indicated by the arrow on the body.
The sole possible leakage is the non-sealing of the seat normally due to the wear of time or to possible
extraneous matters in the pipeline.

FUNCTION
The temperature regulator TR7121-7122 is self-operated without auxiliary energy for controlling the
temperature to the adjusted set point. The valve closes proportionally at temperature changing when the
temperature rises.
The temperature regulator consist of a control valve and a thermostat comprising a temperature sensor, a set
point adjuster, a capillary tube and a working piston.
The temperature regulators operate according to the liquid expansion principle. If the temperature increases
at the sensor, this causes a warming and an expansion of the filling liquid at the same time and therefore the
valve closes over the working piston. While cooling-off this occurs in the reversed sense.
All thermostats are equipped in series with a excess temperature safety device (max. 50°C above adjusted
set point).

OPERATION
VR valve is the type with external pilot. The fluid operates the valve by opening or closing, therefore does not
require any external power. Although there are variations and/or stop of consumption, the valve controls this
dysfunction and contrasts it, maintaining a constant outlet pressure.
The fluid enters the main valve, which is closed and stable with the help of the spring and the power of the
inlet pressure reaches the diaphragm. This pressure flows through the control line and arrives to the
diaphragm via the needle valve, which helps to regulate the overall speed of the main valve. The downstream
pressure is controlled by the valve screw driver, so the maximum pressure enters the upper chamber of the
diaphragm and opens the main valve.

COMMON APPLICATIONS
PRESSURE REDUCING VALVE
The operation and purpose of this type of valve is based
on the reduction of the pressure upstream at a lower
pressure downstream without affecting the pressure
oscillations or the input stream.
This valve will always keep stable the outlet pressure
even if the pressure conditions and/or the input speed are
modified.
PRESSURE REDUCING VALVE WITH DOUBLE PILOT
This valve will always maintain a stable outlet pressure
even if the pressure conditions and/or the input speed are
modified.
It is provided with a second pilot installed on a by-pass
(with its own shut-off valve) that provides a double outlet
pressure with two different values, and it’s able to select
the required pressure simply by opening or closing the
relevant valves.
It’s also used to control water hammers using the outlet
valves as pumps that lead to the tank return pump.
VR
Regulating valve pilot operated
PRESSURE MAINTAINING VALVE
The purpose of this valve is to maintain a constant
pressure of a line. It’s installed on a by-pass of the main
line. When the line pressure increases, the valve detects
the change and opens to evacuate the excess pressure.
PRESSURE REDUCING / MAINTAINING VALVE
The purpose of this valve is to maintain a constant
pressure of a line. It’s installed on a by-pass of the main
line. When the line pressure increases, the valve detects
the change and opens to evacuate the excess pressure.
In addition, also mounts a pilot sensitive to outlet
pressure, necessary to avoid that evacuated pressure
does not exceed the set limit.
LEVEL CONTROL VALVE
The action of this valve controls both the fill and the
discharge of the tank.
When the liquid reaches the maximum height of the tank,
the float closes the valve. When the level drops again,
the valve opens automatically.
VR
Regulating valve pilot operated
ALTIMETER CONTROL VALVE
The purpose of this valve is to control the height of the
liquid in the tank.
The pilot regulator controls the tank outlet pressure and
the altimeter pilot (normally open) maintains the height of
the tank at the relevant level.
FLOW CONTROL VALVE
This valve maintains a constant flow regardless of the
inlet and outlet pressure.
The pilot valve is sensitive to this difference in pressure
on the installed diaphragm. In this way it self-adjusts to
avoid a flow excess and keep it constant.

APPLICAZIONE
APPLICATION
RP01 e RE01 sono posizionatori a semplice e doppio
effetto con segnale in entrata 3÷15 PSI o 4÷20 mA per il
controllo proporzionale di attuatori lineari. Gli apparecchi
confrontano il segnale proveniente dall’unità regolante con
la posizione della leva di feedback collegata all’attuatore.
La comparazione tra queste due forze genera una
pressione di uscita che agisce direttamente sulle camere
dell’attuatore.
The single & double-acting positioners RP01 and RE01
require an input signal of 3÷15 PSI or 4÷20 Ma for
proportional control actuators. The positioner compares
the output signal from a controller with the position
feedback, and varies a pneumatic output signal to the
actuator accordingly. The actuator position is therefore
guaranteed for any controller output signal and the
effects of varying differential pressure.
CARATTERISTICHE
FEATURES
Eccellente risposta dinamica.
Costruzione estremamente compatta.
Regolazione indipendente dello zero e del campo (fig. 1 e
2).
Predisposizione per funzionamento in Split-Range.
Insensibile alle variazioni della pressione di alimentazione.
Staffa regolabile su tutti gli attuatori IEC 534.
Campo della pressione di posizionamento (alimentazione)
regolabile da 0,2..1 a 0,2..10 bar.
Good dynamic response.
Particularly compact design.
Indepentend Zero and Span adjustment (fig. 1 & 2).
Split-Range operation.
Insensitive to pressure variations.

REGOLAZIONE VELOCITA’ VALVOLA
VALVE SPEED ADJUSTMENT
Con i posizionatori RP01 e RE01 è possibile regolare le
velocità di aperture e chiusura della valvola.
Per regolare la velocità dell’attuatore agire sulla vite “A”
(fig. 1).
With RP01 and RE01 a splitted opening/closing speed
adjustment can be made by simply turning a screw.
To adjust the actuator speed operate on screw “A”
(fig. 1).
INVERSIONE DELL’AZIONE
REVERSE ACTION
I posizionatori vengono forniti per il funzionamento in
azione diretta. Per invertire l’azione è sufficiente svitare il
tappo dall’uscita “OUT2” e inserirlo nell’uscita “OUT1”.
The positioners are normally supplied for direct action. In
case the reverse action is requie, then remove the plug
from “OUT2” and put it inside the “OUT1”.
FUNZIONAMENTO A DOPPIO EFFETTO
DOUBLE ACTING OPERATION
I posizionatori RP01 e RE01 offrono la possibilità di
essere utilizzati sia come posizionatori a semplice effetto,
che come posizionatori a doppio effetto.
Both RP01 and RE01 units are designed to operate as
single or double acting positioners. In this way, they
highly improve the control valves operations.

Sensore induttivo / Inductive sensor
APPLICAZIONE
In alcuni tipi di applicazioni definite, gli interruttori di prossimità
ad elevata distanza di commutazione facilitano la soluzione dei
problemi di rilevamento, per es. in caso di spazi limitati, di
oggetti di piccole dimensioni ed in caso di fattori di riduzione
sfavorevoli.
Va detto inoltre che giocano un ruolo molto importante nel caso
di scarse possibilità di regolazione, nel caso di tolleranza di un
gioco meccanico grande e nell’impiego di rivestimenti protettivi.
APPLICATION
For some applications proximity sensors with increased
switching distance can be used to solve detection problems
such as small object detection or overcoming the effects of
material dependent reduction factors.
In addition, these extended range sensors may be used to solve
issues such as mounting restrictions, mechanical tolerances or
for detection through protective coatings.

NCB2-12GM35-N0 ATEX
Sensore induttivo / Inductive sensor
APPLICAZIONE
In alcuni tipi di applicazioni definite, gli interruttori di prossimità
ad elevata distanza di commutazione facilitano la soluzione dei
problemi di rilevamento, per es. in caso di spazi limitati, di
oggetti di piccole dimensioni ed in caso di fattori di riduzione
sfavorevoli.
Va detto inoltre che giocano un ruolo molto importante nel caso
di scarse possibilità di regolazione, nel caso di tolleranza di un
gioco meccanico grande e nell’impiego di rivestimenti protettivi.
APPLICATION
For some applications proximity sensors with increased
switching distance can be used to solve detection problems
such as small object detection or overcoming the effects of
material dependent reduction factors.
In addition, these extended range sensors may be used to solve
issues such as mounting restrictions, mechanical tolerances or
for detection through protective coatings.

Box micro / Limit switch box
CARATTERISTICHE
Costruzione idonea per essere installata in ambienti interni ed esterni.
Indicatore di posizione tridimensionale.
La regolazione delle camme è di tipo micrometrico ottenuta per mezzo di un accoppiamento mille-righe. La posizione
delle camme è assicurata da una molla che ne impedisce lo spostamento accidentale. La regolazione viene effettuata
manualmente senza l’ausilio di alcuna attrezzatura particolare.
La scheda elettrica è provvista di una morsettiera, predisposta per un eventuale cablaggio dell’elettrovalvola montata
esternamente.
Il coperchio viene posizionato correttamente sulla scatola grazie a due punti di centraggio. Le viti di fissaggio sono del
tipo anticaduta, cioè in caso di apertura del coperchio, rimangono ancorate ad esso.
Le schede elettriche sono state progettate affinché siano tutte intercambiabili e facilmente sostituibili senza dover
smontare lo stelo.
Il castelletto, in AISI 304, è stato progettato per un immediato montaggio sugli attuatori pneumatici, in accordo alle
normative VDI/VDE 3845 NAMUR.
La scatola è provvista di due connessioni filettate M20x1,5.
FEATURES
Construction suitable for indoor and outdoor installation.
Visual position indicator.
The sitting of the cams is a micrometrical one, and it’s obtained by spline connection. The position of the cams is
ensured thanks to a spring, which acts preventing any casual movement. The regulation is performed manually without
any particular tool.
The electric card is supplied with a terminal strip, that is arranged for a possible harness of the outside mounted
solenoid valve.
The cover is correctly positioned on the box thanks to two centering points. The fastening screws are kept in their seat,
so as not to get lost once the box is open.
The stainless steel 304 bracket has been conceived for an immediate assembling on the pneumatic actuators, in
accordance with VDI/VDE 3845 NAMUR standards.
The box has two conduit entries threaded M20x1,5.
