Ductile Iron Butterfly Valve Gearbox/Lever Operation Flange End

Wafer type butterfly valve

1. PROFUCT PROFILE

Wafer type butterfly valve is one type of central lined butterfly valve, which is one normal type of butterfly valve in need of big quantity.Butterfly valve flange type has its flanges with holes. The pipe end to be connected to the valve is also designed with a flange and holes of the same size as those on the flanged valve. The valve is secured on the piping system using bolts and nuts.Prosper Flow can produce the wafer butterfly valve rubber lined in accordance with EN593, API609 and AMSE B16.34.

2. FEATURES
