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.
