MM Low Cost Valve Series

Brand: Proportion-Air, Inc

The MM-Series is a low cost, closed-loop valve offering electronic control of pressure from full vacuum up to 175 PSI.

A variety of analog signals are available and multiple mounting options; DIN rail, panel or manifold mount up to 12 MMs on a sub-base manifold.

The MM pressure control valve is extremely durable and able to withstand industrial environments, traditional shop air and vibration, while easily controlling pressure based on the user’s command signal.

An analog monitor output signal is standard on all MMs. This device is designed to work in static (deadheaded) applications. It can be configured for external feedback to accept a load cell or another type of transducer as 2nd loop input.

The MM-Series can control vacuum, low pressure and vacuum thru positive pressure in the same unit.
