Pinch Valve

Pinch Valve
Pinch Valve

A pinch valve is a control valve that opens and closes by squeezing an internal rubber sleeve. With the medium contacting only the rubber sleeve, it features a full-bore unobstructed flow path, zero leakage, anti-clogging, and wear-and-corrosion resistance. It is suitable for pipeline control of high-particulate or highly corrosive media such as slurries, sewage, and powders.
