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.
H8819 SERIES
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
signal.
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.
