Yuken EDG Pressure Relief Proportional Valves

Yuken pressure relief proportional valves

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 Yuken pressure relief proportional valves installation place is to put the bleeder upward in order to eliminate the presence of air in the oil passage when it have a
trial ramming; If use together with another main valve, the guide piping can not exceed 30 cm to make the pressure be more steady
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.
