Single-Use Pinch Valve

For on/off flow control

Pinch Valve Technology

Pinch valves are often used in single use applications for on/off flow control. As the valve does not get in contact with the process media it does not require replacement of any parts. For non-pressure designs simple solenoid-driven pinch valves can be used, but when pressure needs to be applied, such as in filtration equipment the significantly tougher tubings together with the internal pressure pose a significant burden to the pinch valve and standard solenoids normally cannot do the job.

A newly developed design allows for on/off control of pressurized single-use tubings in a compact package. The tubing firmly sits in a well-defined, hose size adaptable bed which guarantees uninterrupted operation for many cycles. The valve can easily be installed within a cabinet with only the actuated part being visible.
