Wafer Type Butterfly Valves
Bronze Disc Wafer Butterfly Valve
Bronze disc wafer butterfly valve; a wafer type butterfly valve with GGG40.3 ductile iron body, aluminium bronze disc and NBR seal, installed between two pipe flanges and secured with bolts. Aluminium bronze exhibits high resistance to the erosive effects of seawater, making it ideal for marine, shipyard and coastal facility seawater lines.
Operates up to +90 °C with NBR seal. Operating pressure is PN16 in the DN40–DN300 range, PN10 in the DN350–DN600 range; flange connection is PN16. Manufactured to TS EN 593 standard.
