The WAM® VM Pinch Valve is a full bore, normally open control valve used to regulate the flow of powders, granules, fibers, dense mixtures or liquids in pneumatic conveying systems and other pipelines. As a safety shut-off valve on silo fill pipes, should excess pressure build inside the silo or the silo over-fill, the Valve is instantly and completely "pinched" closed to prevent any further filling or over-pressurization. WAM® VM Pinch Valves are compact, low weight, and require little maintenance.

Advantages
