Product Overview
The HAWE EMP 31 V 80 is a precision proportional relief valve engineered by HAWE Hydraulik, a globally recognized manufacturer of high-quality hydraulic components. This valve operates on a direct-operated, solenoid-controlled proportional principle, enabling stepless, infinitely variable adjustment of system pressure in proportion to the electrical input signal. Unlike fixed-setting relief valves, the EMP series allows for dynamic pressure regulation, making it an essential component in industrial hydraulic systems requiring precise force control, load simulation, or energy-efficient pressure management. The “V 80” designation indicates a specific pressure rating and flow capacity configuration, ensuring compatibility with medium-to-high pressure circuits. Its robust construction and precise spool-to-sleeve fit ensure minimal hysteresis and excellent repeatability, critical for closed-loop control applications.
