The TUBE-O-MATIC® has been designed to include the excellent features of a pinch valve without the inherent weaknesses. The tube sleeve in the TUBE-O-MATIC® does not collapse entirely as the tubing does in a typical pinch valve. Our tube closes on the airfoil center core when cycling. Because of this design, the travel of the tube (the only moving part inside the valve body) is substantially reduced, which leads to an extended service life of the valve.

The normally open TUBE-O-MATIC® valve design allows media flow in both directions. This feature can prove invaluable in systems requiring both forward and reverse control of media flow.

Our tube is controlled by an external pneumatic or hydraulic pilot pressure signal. To close the valve, pilot pressure is applied, closing the tube around the center core and sealing bubble tight. To open the valve, pilot pressure is exhausted, allowing full flow. The small tube deflection permits a high cycle rate with minimal flow noise and shock-free smooth opening or closing when using fluids. Our design 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.

With a Cv range of 4.0 to 75.0 and pipe sizes available from 1/4" NPT to 2 1/2" NPT, TUBE-O-MATIC® offers a valve to fit any application. The airfoil design of the center core and the straight-through flow path result in flow capacities that compare to ball valves. Click here for an inside view and to see how it works.
