Proportional Electro-Hydraulic Pilot Relief Valves



This valve consists of a small DC solenoid
and a direct-acting relief valve. It serves
as a pilot valve for a low flow rate hydraulic
system or a proportional electro-hydraulic
control valve and controls the pressure in
proportion to the input current.
This valve is used in conjunction with
the applicable power amplifier


  • Component of DC current solenoid and vertical type relief valves.
  • Proportional coil enable un-stage pressure correspondence to input current.
  • Power amplifiers for option use.
