Air-Operated Pinch Valve

Air-Operated Pinch Valve

Pinch valves are ideal valves for fluids containing solid particles or contaminants to isolate and regulate pipelines. Because the sleeve is the only part in touch with the medium, it is extremely resistant to wear and corrosion. Even if complicated chemical processes are occurring in the pipeline, the pinch valve is still easy to handle them. Its applications include power plants, sewage treatment plants, mining, and chemical process control.
