EDG Hydraulic Proportional Relief Valves 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. Note that this valve is used in conjunction with the applicable power amplifier.The EDG series of Yuken pressure relief proportional valves can simplify hydraulic piping system and improve traditional complicated piping of one pressure with one remote control valves. Our good qualify of proportional coil produces step-less type of pressure upon input current to display the best function unifying hydraulic and electronic.
The EDG hand adjusting screw can be turned in clockwise direction in order to restore to the origin at usual time if the electric control is disorder and need to supply pressure occasionally.
