How it works... An Airpinch™ valve is a pinch valve.  Air or liquid pressure at the control inlet collapses the internal rubber sleeve to provide immediate and positive shut-off.  The rubber sleeve closes completely, even on large particulate matter, abrasive and corrosive materials.  When open, the sleeve allows full, unobstructed flow with little turbulence.  Airpinch™ pinch valve sleeves can be easily and economically replaced when they wear out.
