Resolution Air Proportional Pinch Valves


Proportional Pinch Valves

Sanitary, non-contact, high resolution flow control

Flow Metering and Fluid Separation

Fluid separation and flow metering are now available in one high performance valve. Resolution Air, Ltd.’s unique valve design allows the benefits of pinch valve fluid separation to be combined with proportional valve control for sanitary processes requiring highly accurate fluid metering where cleanliness and sterility is required.

A Better Alternative to Traditional Solenoid Pinch Valves

A primary benefit of proportional pinch valves is automating the metering process of liquids and gases in open and closed loop control systems. In addition, Resolution Air, Ltd valves are also being utilized in applications requiring simple ON/OFF control because they generate significantly higher pinch forces (5x) compared to a traditional solenoid pinch valve. As a result, our valves are quickly replacing traditional low force solenoid pinch valves in many markets including medical device and life sciences, where precise sanitary fluid metering is critical to the application.
