Produces air actuated pinch valves that can provide immediate, positive shut off of liquids & dry flowables. These valves are normally open & will require constant pressure for sustained closure with a maximum control (air) pressure of 90 PSI. Typical differential control pressures are 20 PSI greater when controlling liquid media & 40 PSI when controlling air. Liquid may also be used for actuation. These valves are suited for applications involving abrasives, highly viscous & corrosive materials.
