On-Board Electro-Hydraulic Products


Electro-Hydraulic Proportional Relief Valves
Relief valves with manual control allow you to simply regulate maximum pressure. Models with electric vent control are available in either “normally-open” or “normally-closed” configurations.
Electro-hydraulic models provide remote control for infinitely variable pressure settings up to the maximum pressure.
50 GPM at 15,000 PSI (190 l/min. at 1040 bar)
75 GPM at 9,000 PSI (284 l/min. at 620 bar)

H8819 Series


Electro-Hydraulic Remote Proportional Actuators

A Remote Proportional Actuator (RPA)
produces output rod displacement
proportional to an electrical input
The RPA can be used to remotely
control variable displacement pumps
and motors. It can also stroke spools
of large valves, throttle controls,
clutches or brakes.

Electro-Hydrauic Valves


  • The sensor in directional control valves is to monitor the spool position.
  • Valves without sensor are also available in both pressure control valves and directional control valves.
  • Open-loop types are also available.
  • EHDFG-04 and 06: 24V DC power supply is needed.
  • EHDFG-01, 03, 04 and 06: 0 to 5V DC command signal is needed.
  • EHDFG-04 and 06: The spool displacement is shown as a percentage.
