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.In the case of a Wafer-style butterfly valve, the body is annular with a few non-tapped centring holes. Some Wafer types have two while others have four.
The flange bolts are inserted through the bolt holes of the two pipe flanges and the centering holes of the butterfly valve. By tightening the flange bolts, the pipe flanges are pulled towards each other and the butterfly valve is clamped between the flanges and held in place.Prosper Flow can produce the wafer butterfly valve rubber lined in accordance with EN593, API609 and AMSE B16.34.
