Cast iron butterfly valve DN450 type WAFER, reducer drive, stainless steel disc, for ø450mm pipe.
Device to interrupt or regulate the flow of a fluid in a duct, increasing or reducing the passage section by means of a plate, called a "butterfly", which rotates on an axis.
By reducing the passage area, the local pressure drop in the valve increases, reducing the flow.
They are used in air ducts, pipes for liquids and in mechanical applications, such as in some types of heat engines.
Makings:
Body in ductile cast iron GGG-40.
EPDM elastomer
PN10 working pressure
With centering lugs for quick and easy installation.
With long neck for insulated installations.
All the pieces are identified with the casting number of the foundry, for quality control.
The absence of pins and screws in the Butterfly, with the drive of the shaft, avoids risks of corrosion and the formation of impurities.
Monobloc axle in one piece, avoiding breakage with possible water hammer.
The anchoring system of the elastometer with the body prevents it from moving during maneuvers, thus guaranteeing its durability.
Manufactured under the EN / 593 / BS5155 / MSS SP-6 standard.
