Miniature Proportional Pinch Valve M-Series

Precision Flow Control Pinch Valve
Providing Sanitary Fluid Separation & Flow Metering

Resolution Air’s valve design 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 is required. Previously, this could only be accomplished with a manually operated control valve. The newly developed Miniature Proportional Pinch Valve series has been engineered to meet the needs of the most challenging precision flow applications in industries such as bio-chemical, food and beverage, and healthcare.

Miniature Proportional Pinch Valve Design

The MPPV series allows physical separation between 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 through the tube. The design incorporates a stepper linear actuator and custom piston, which provide precision proportional control functioning in the valve. In addition, with the actuator’s non-back driveable lead screw, power is only required when changing position.

Available in a variety of size configurations to meet a wide range of needs, Resolution Air Miniature Proportional Pinch Valves are ideally suited for use in portable and handheld equipment designed for analytical and diagnostic processes.
