Miniature pinch valve, IPU linear Piezoelectric Pinch Valves, accurately control the flow of high-purity fluids, corrosive and other liquids and gases in pharmaceutical medical and biotechnology environments.

Processor-controlled pinch valves that directly accept a 4-20mA or 0-5 VDC control signal inputs.

IPU Pinch Valves are available in normally closed, normally open or Latch, and are used with 1/16 (1.6 mm) OD to 3/8″ (9.5 mm) OD Soft Tubing. Read more…

Customer-supplied tubing is inserted through the valve and connected to the process. The tubing can be snapped in from the side without removing it from the process.

A plunger activated by a piezoelectric actuator with rounded pinch element moves in 0.001 mm (0.00002 inch) increments to precisely squeeze the tubing for accurate, proportional flow control. The plunger is capable of providing a force of up to 500 grams
