Proportional Valves

HYDAC offers a wide range of Electrically Operated Proportional Pressure Relief Valves and Pressure Reducing/Relieving Valves. These proportional valves vary the output pressure in response to a variable electric input.

HYDAC electrically controlled, pilot operated proportional pressure relief valves are available with pressure ranges up to 5000 psi (350 bar). Models are available for flow rates up to 79 gpm (300 lpm).

HYDAC electrically controlled, direct acting and pilot operated proportional pressure reducing/relieving valves are available with pressure ranges from 200 psi (14 bar) up to 5000 psi (350 bar). Models are available for flow rates up to 16 gpm (60 lpm). Pressure control valves can be used to regulate the pressure applied to hydraulic actuators.

Electric current controls with PWM are recommended to be used for HYDAC Proportional Valves.
