Sanitary High Resolution Proportional Pinch Valve by Resolution Air, Ltd.

Share Article

Fluid separation and flow metering are now available in one high performance valve.

New technology developed by Resolution Air, Ltd. allows the benefits of pinch valve fluid separation to be combined with proportional valve control for sanitary processes that require highly accurate, incremental flow regulation where cleanliness and sterility are required. The newly developed and patent pending Miniature Proportional Pinch Valve series has been engineered to meet the needs of the most challenging precision flow applications in industries such as biochemical, food and beverage, and healthcare.

The MPPV series design physically separates the valve from corrosive or high purity process fluids, while providing the incremental flow control offered in a conventional proportional valve. The MPPV pinches a fluid filled, pressurized, low durometer tube to regulate the flow of the liquid or gas flowing through the tube. The design incorporates a stepper linear actuator and custom piston with an elastomeric seal, which provide precision proportional control functioning in the valve. In addition, due to the actuator’s locking lead screw, power is required to change position only. Standard valve sizes for 1/8",1/4",3/8",1/2" O.D. Tube. In order to simplify initial evaluation of the Miniature Proportional Pinch Valve, Resolution Air, Ltd. also offers the MPPV-DK demonstration kit which will have you up and testing in 10 minutes.
