Stainless Steel Pnematic Operated Wafer Butterfly Valve
Description
Pneumatic wafer butterfly valve is a kind of mid-line soft-seal butterfly valve with good sealing performance. The sealing materials include rubber, polytetrafluoroethylene, etc., and the leakage can reach zero. Due to the limitation of structural characteristics, pneumatic soft-seal butterfly valve is not suitable for high temperature, high pressure and anti-wear industries. It is only suitable for switching and regulating flow in normal temperature environment and low pressure, medium pressure and other places.
