INTRODUZIONE
FOREWORD
In generale, le valvole a farfalla a tenuta inelastomero
stanno trovando sempre maggiore diffusione, grazie alla
loro comprovata affidabilità ed ai molteplici vantaggi che
esse offrono rispetto alle valvole tradizionali. In particolare,
le valvole a farfalla serie 301, trovano applicazione
nei più svariati settori industriali, sia per intercettazione che
per regolazione di qualsiasi tipo di fluido.
La sua particolare progettazione consente di soddisfare a
quanto richiesto dalle industrie siderurgiche, navali, tessili,
alimentari, chimiche, petrolchimiche, trattamento acque,
tintorie, ecc. nonché nel settore impianti di
condizionamento e riscaldamento. Principali pregi delle
valvole a farfalla sono:
-l'ingombro ed il peso particolarmente ridotto, che facilita
l'installazione sulla tubazione anche in quegli impianti dove
gli spazi disponibili sono alquanto ristretti;
-sede di tenuta in elastomero con anello metallico interno,
che oltre ad assicurarne la stabilità geometrica e
dimensionale, ne facilita, in caso di rotture accidentali
dovute ad interposizione di corpi estranei, la sua
sostituzione, senza richiedere l'intervento di personale
specializzato. Inoltre, la sede di tenuta protegge il corpo
valvola dal fluido di passaggio, per cui esso può essere di
materiale non particolarmente pregiato e nello stesso
tempo, ricoprendo parzialmente i fianchi del corpo, dato il
profilo particolare, permette di avere una valvola già
pronta al montaggio sulla tubazione, senza necessità di
ulteriori guarnizioni. L'otturatore autocentrante, dovuto
all'accoppiamento flottante dello stesso sull'albero, di forma
lenticolare, rappresenta un ottimo mezzo per ridurre le
perdite di carico attraverso la valvola e data la precisa
lavorazione del bordo, ne assicura, per interferenza con la
sede in elastomero, la perfetta tenuta fino a 21,5 Bar e in
depressione a 10
TORR, consentendo solo la perdita
dovuta alla permeabilità molecolare dell'elastomero. Inoltre
sull'otturatore non é presente alcun elemento di fissaggio
con l'albero, potenziale causa di inconvenienti e di
corrosione, per cui garantisce maggior sezione di
passaggio, basse perdite di carico e minor turbolenza.
Per concludere si può affermare che la valvola a farfalla
rappresenta un organo di intercettazione ideale per
pressioni di esercizio che vanno dal vuoto ad oltre 20 Bar,
e con temperature dipendenti dal tipo di elastomero scelto
per la sede di tenuta.
Generally speaking, butterfly valves with elastomer seat
are finding increasingly wider application thanks to their
well proven reliability and the many advantages they have
to offer compared with conventional valves.
Above all, the series 301 butterfly valves find
application in widely differing industrial sectors for both
shut-off and flow control service regarding any type of
fluid.
The valve design is such as to be able to meet requirements
in the iron and steel, ship building, textile, chemical, and
petrochemical industries, in water treatment processes and
dyeing plants, etc. as well as in the air conditioning and
heating sector.
Main advantages of the butterfly valves are:
-very compact size and light weight; this facilitates
installation on the piping also in special plants with limited
amount of free space.
- elastomer seat with internal metallic support ring which
ensures geometric and dimensional stability as well as easy
replacement of the seat without requiring the services of
skilled personnel, in the event of accidental breakage due
to infiltration of foreign matter.
Moreover the elastomer seat protects the valve body from
the process fluid, hence the body need not be of special
material. The seat also partially covers the sides of the valve
body thanks to its special shape, therefore the valve is
already ready for mounting on the piping without needing
additional seals..
The disc it self-centering thanks to the floating coupling of it
on the stem and is of lenticular shape. It represents an
excellent means for minimizing pressure drops across the
valve. Moreover, thanks to the accurate machining of its
edge, it ensures, through interference fit with the elastomer
seat, perfectly tight shut-off up to 21,5 bar and vacuum
tight up to 10
TORR. The only loss is that due to the
molecular permeability of the elastomer.
Moreover the disc has no fastening element with the stem,
which is potential cause of problems and corrosion; hence
there is improved full flow, lower pressure drop and less
turbulence.
To sum up, it can be stated that the butterfly valve represents
an ideal shut-off device for operating pressures ranging
from vacuum to over 20 bar, while the temperatures depend
on the type of elastomer choosen for the seat.

The flanges (better if with neck or socket type) should be
always perfectly parallel with well machined surfaces: the
inner and outer diameters must be machined in compliance
with the actual flanges norms.
lf the flanges are not parallel or not well machined, they
would cause abnormal stress on the tie-rods resulting in a
poor tightening with the seal.
Consequently the disc movements would cause rapid wear
of the seat. Moreover inner and outer diameters of the flanaes
are very important for a correct valve operation.
lf the diameters are too small (fig. A), they could prevent
valve movement.
Too large diameters, instead, (fig. B), would not allow sufficient

Pressure rating of the S buttefly valves are as follows: DIN NP2.5 - Np6 - Np10 - Np16. Testing pressures for the above rating at the temperature of 38°C/+100.4°F are:
- Hydraulic test of the valve body (with disc in open position) at a pressure 1.5 times the nominal pressure;
- Hydraulic test for tight shut-off (with disc in the closed position) at a pressure 1.1 times the nominal pressure;
- Pneumatic pressure for tight shut-off at 7 bar.

Hydraulic test of the valve body at a pressure of 28.9 bar - Hydraulic testing for tight shut-off at a pressure of 19.3 bar - pneumatic test for tight shut-off at 5.6 bar. Valves can also be supplied
with shut-off reduced to 3.5 bar for low pressure services. The latter offer low torque values, just like those for adjustment service, where the interference between the disc and the seat is
pratically zero.

! MAINTENANCE
Please note that fluid residues inside the butterfly could be dangerous for humans and
the environment. The butterfly valve must be handled and cleaned carefully prior to the
maintenance. The maintenance is made at the own risk of the user. Maintenance on a
S301 must be executed by trained staff only. Only original spare parts are to be used.
No maintenance and/or periodic lubrification is required.The various component parts of
the valve can be inspected or removed quickly using normal tools. To do so, close the
valve; then remove the tie-rods or bolts from the flanges and extract the valve off the
piping.

DISASSEMBLY AND REASSEMBLY
First fully open the valve. Remove the lever system or operating mechanism fitted
on the valve.
Then unscrew the plug (11) and remove seal (10). Extract the upper stem (2), the
lower stem (3) together with the stem O-rings (4) and remove the eventual seals of
the bushings (5-9-15). Force the disc (12) out from the seat (13), and then the same
seat, making slow strokes with a rubber mallet. Inspect and/or replace the parts
where necessary, then reassemble all the items in the reverse order of the
assemblying. Reassembly is gratily helped applying smearing small amounts of
silicone grease inside the valve body and on the two stems. At the end pay attention
in perfectly aligning the square end of the upper stem with the broaching of the disc.
In fact, there is risk of damage if repeated use of force is made when inserting the
stems in case the holes on the seat are not properly aligned with the corresponding
ones on the valve body and disc.
SPARE PARTS
Normally the valves are supplied with the disc open in the measure of few degrees and
therefore they should be installed between the flanges of the piping. After tightening all
the tie-rods or bolts, perform the opening and closing manoeuvres to make sure there
are no assembly faults as mentioned above. If everything is OK, the valve can operate
for very long periods without requiring inspection or spare parts.The only recomended
spare parts for valves are the rubber ones i.e. the seat on the valve body (13),
with its respectively o-rings (16) where they are present, the o-rings for stems and

In nomogramma qui riportato può sostituire, per la sua praticità e semplicità di lettura, nonché per la sua sufficiente esattezza, la formula del coefficiente
di portata CV, solitamente usata.
Tale nomogramma può essere usato sia per i gas, con velocità superiore a 4.5 m/sec, che per i liquidi (parte gialla), mettendo in relazione i valori di
portata Q, il diametro Ø, l’angolo di apertura α e la caduta di pressione Δp delle valvole a farfalla .
C’è da considerare inoltre, l’economicità del sistema di regolazione con le valvole a farfalla, poiché buone regolazioni si possono ottenere per i valori
d’angolo di apertura del disco compreso tra 25° e 70°.
The nomograph plotted alongside can replece the normally used flow coefficient CV based formula as it is pratical, easy to read and sufficiently
accurate.
Such nomograph can be used both for gases with velocities exceeding 4.5 m/sec and for liquids (coloured yellow) by plotting the flow rates Q, diameter Ø,
angle of opening and pressure drop of the butterfly valves in relation to each other.
The economic advantages of the adjustement system with butterfly valves should also be considered as good adjustement can be obtained for disc
opening angles ranging from 25° to 70°.

La caduta di pressione della valvola in condizioni di massima apertura
(90°).
Procedendo come si è fatto per il liquido, si ricava che la caduta di
pressione della valvola è di 2.16 Bar: questo valore è però relativo
all’acqua.
Il Δp relativo all’aria sarà di:
The presure drop across the valve under conditions of maximum opening
(90°).
Proceed as described above for the liquid, to deduce that the pressure
drop across the valve is 2.16 bar: however this value is referred to water.

disco e per angolo di apertura α = 75°.
Proiettare orizzontalmente dal punto Q = 250 m3/h fino ad incontrare la
curva della valvola (DN 200 mm), indi proiettare verticalmente fino ad
intersecare la linea di massima apertura (90°), e infine orizzontalmente
sull’asse della caduta di pressione, dove si legge il valore di 0.00827 Bar.
Continuando a proiettare verso l’alto fino ad intersecare la linea α = 75°,
si può leggere in corrispondenza all’intersezione, un valore di caduta di
pressine di 0.0165 Bar.
The pressure drop across the valve under conditions of maximum disc
opening and angle of opening α = 75°.
Proyect horizontally from point Q = 250 m3/h until meeting the valve curve
(ø8”) then project vertically until intersecting the line corresponding to
maximum opening (90°). Lastly project horizontally on the axis referring
to the pressure drop, where a value of 0.00827 bar is read off.
Continue to project towards the top until intersecting the line α = 75°
where a pressure drop of 0.0165 Bar can be read at the point of
intersection.

MONTAGGIO - ASSEMBLY
Inserire la valvola tra le flange di accoppiamento in modo corretto, interponendo tra esse e la valvola delle comuni
guarnizioni a cartella esenti d’amianto, rispettando la direzione del flusso. Essa viene centrata automaticamente
dai tiranti della flangia di accoppiamento e può essere installata sia su tubazione orizzontale che verticale (fluido
ascendente).
Attenzione: evitare l’installazione della valvola in prossimità di correnti pulsanti.
NOTA: usare normalmente flange a saldare di testa-tasca o filettate per flange slip-on, specificare all’atto dell’ordinazione.
Insert the valve between the mounting flanges in the correct way, placing some simple asbestos-free flat seals between
them and the valves, and according to the direction of the flow.
The valve is automatically centered by the bolts of the mounting flange and can be installed both on horizontal
and vertical piping (rising fluid).
Caution: avoid installing the valve close to pulsating streams.
NOTE: Normally use butt welding, socket welding flanges or screwed flanges: for slip-on flanges, please specify
when ordering.
APPLICAZIONI - APPLICATIONS
Scegliere adeguatamente il diametro della valvola, in modo che la velocità del fluido, attraverso il foro di passaggio B, non sia superiore ai seguenti valori: Prodotti liquidi 5 m/sec. - Prodotti gassosi 25 m/sec. In apertura, il clapet della valvola sviluppa un angolo massimo di 60° circa ed è superfluo che tale valore sia superiore, pioché l’area sviluppata è maggiore di quella relativa al foro di passaggio.
Choose the correct valve size so that the velocity of the fluid througt port B does not exceed the following levels:
Liquid products 5m/sec - Gaseous products 25 m/sec. When the valve is opened, its disc develops a maximum
angle of approx. 60°. It is superfluous for such angle to be greater as the developed area is greater that of the
port.
MANUTENZIONE - MAINTENANCE
Le valvole di non ritorno non necessitano praticamente di manutenzione, eccetto l’eventuale sostituzione dell’O-ring di tenuta. In condizioni particolarmente severe di lavoro, controllare periodicamente l’O-ring di tenuta. Per condizioni normali di lavoro, si raccomanda il controllo della valvola dopo
2 o 3 anni di servizio.
check valves do not require pratically any maintenance, except the replacement of the O-ring, when necessary. Periodically check the O-ring
when operating under severe conditions. It is advisable to inspect the valve after 2 or 3 years service, under nirmal operating conditions.
NOTA: Su richiesta si possono fornire valvole corredate di contrappeso e valvole senza O-ring di tenuta per temperature superiori a 250°C.
NOTE: Valves can be supplied complete with counter weight or valves O-ring for temperatures exceeding 250°C / +482°F, on request
