Miniature Proportional Pinch Valve-IP65 Rated Series

mppv-en series

Sanitary Flow Control Pinch Valve

Fluid separation and flow metering in one precision pinch IP65 rated valve.

Expanding on the patented Resolution Air MPPV-series, the MPPV-EN series provides protection against dust and water jet ingress. The addition of a IP65 rated enclosure offers further value for the MPPV technology in sanitary processes.

The MPPV-EN series enclosure means barriers associated with environmental conditions are eliminated. This IP65 rated valve makes the advantages of the MPPV design attainable for a wider range of systems and applications. The incorporation of robust M12 connector technology streamlines installation and wiring, adding to MPPV-EN series advantages.

Not only do the MPPV- series and MPPV-EN series provide fluid metering, both are capable of generating 5x (15 lbs.) the pinch force of a typical solenoid pinch valve. This is a tremendous benefit in systems utilizing higher pressures and larger tube diameters (1/8” O.D. -0.500” O.D.).

Available in a variety of size configurations to meet a wide range of needs, the newly developed MPPV-EN series has been engineered to meet the most challenging precision flow metering needs in industries such as bio-chemical, food and beverage, and medical devices.
