Bolts for Wafer butterfly valves
How to determine the bolt length for the connection between the wafer butterfly valve and the flange?
STV Valve organizes the specifications and quantities of the wafer butterfly valve bolts for everyone, so that the length of the wafer butterfly valve bolts can be determined.
With a Wafer valve, a longer bolt or threaded rod is used that passes right through both flanges and the valve. This pulls the flanges together which holds the valve in place.
The Wafer type Butterfly Valve is placed between pipe flanges, and the flange bolts surround the valve body. The Wafer Type Butterfly Valve is suitable for most flanges (including Table E, PN16 and Ansi150). If either side of the valve needs maintenance, then the entire line must be shut down.
