MPV High Resolution Valve Series

Brand: Proportion-Air, Inc

The MPV – Ultra High Resolution, manifold mount – electro-pneumatic closed-loop proportional pressure control valve.

The MPV-Series utilizes a variable orifice valve on the inlet side which eliminates the digital steps of traditional ON/OFF solenoids.

The field adjustable hysteresis potentiometer allows users to virtually eliminate the dead-band of the control circuit, resulting in superior system resolution, accuracy and repeatability.

Ideal for very sensitive applications such as leak testing at low pressures, dispensing in micro units and microfluidics applications.

Din-Rail, panel mount or up to 12 stations on a sub-base manifold are the mounting options for the MPV1 high resolution, manifold mount controller.
