Miniature Proportional Pinch Valves

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, 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.

MPPV Advantages

The accuracy, separation, and flow of the MPPV is unprecedented. Until now, the only comparably similar valves have been manually operated or extremely large, bulky, and expensive. The Resolution Air Miniature Proportional Pinch Valve eliminates all of those issues, and is available in a variety of size configurations to meet a wide range of needs. The MPPV is ideally suited for use in portable and handheld equipment designed for analytical and diagnostic processes.
