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
  • Full Bore Design prevents pressure loss and material turbulence
  • Requires only 28 PSI differential pressure to pinch shut but can withstand up to 37 PSI Max DPM
  • Easy and quick replacement of NR-Sleeve
  • NR-Sleeve material is fabric-reinforced and flexible for long life
  • Valve is compact and lightweight using an aluminum alloy Valve body
  • Stock available in 3", 4", 5" or 6" to handle the majority of applications
  • Maximum Bladder Working Pressure: 52 PSI, but Bladder can withstand up to 90 PSI inflation pressure
  • Working Temperature: 10°F to 180°F
