Product Overview
The HAWE PRL400PC06P18 D1 is a precision proportional pressure reducing valve engineered by HAWE Hydraulik, a globally recognized manufacturer of high-performance hydraulic components. Operating on a direct-operated, proportional solenoid principle, this valve continuously and steplessly regulates secondary system pressure in proportion to an electrical command signal, independent of fluctuations in primary pressure and flow. As a normally open pressure reducing valve, it maintains a stable, infinitely variable outlet pressure for downstream circuits, making it an essential control element in demanding industrial hydraulic systems requiring precise force, torque, or pressure modulation.
