Our 2 1/2" TUBE-O-MATIC® solenoid pilot-operated pinch valve is designed to tolerate fluids, liquids, acids, slurries, and many forms of abrasive material without the inherent weakness of other valve types. Compared to competitor pinch valves, our tube sleeve closes on the airfoil center core while cycling, substantially reducing the tube's traveled distance and extending the valve's longevity. The normally open design allows flow in both directions making it compatible in systems requiring bi-directional control of the media. Additionally, this valve is designed and tested to provide bubble-tight closure for optimal performance.
Cv ranging from 4.0 to 75.0
Easy in-line repair - saves on machine downtime
Controlled by an external gas or liquid pilot pressure signal via an AC or DC solenoid
The small tube deflection allows a high cycle rate with minimal flow noise and shock-free smooth opening or closing when using fluids
Configurable to your specific application
For Air, Inert Gases, Liquids, Abrasive or Corrosive Media
Features a straight-through flow path that eliminates the build-up of solids in the valve body, causing it to act as a self-flushing unit.

For maximum tube life, the pilot-to-media pressure differential should not exceed 20 PSI. For line pressures below 50 PSI, pilot pressure must be line pressure plus 15 PSI.
