Proportional Pressure Reducing Relieving Valve

A customer wanted to improve the performance of an off-highway vehicle by replacing the component that controlled the main stage of a hydraulic valve. Designed as a continuously variable, normally open valve, this proportional valve operated over various pressure ranges to optimize controllability.

Proportional  Pressure  Reducing  Relieving  Valve
