EFBG Proportional Relief Valve PDF

EFBG hydraulic proportional pressure flow control valve is used to control pressure and flow separately in hydraulic system through two electric signal, it can trace load pressure with a small differential pressure in order to control the output power of pump. In other words, it is an energy-saving valve, since the valve loads the pressure and keeps min. pressure difference to control the pump output power, therefore, it is a low-energy, energy efficiency, inlet throttle control adjustment valve. The EFBG has a temperature automatic supply function, it allows to control the flow stable and not affected by the oil temperature.

Additional Indication:

1.Installation position: The correct position for EFBG valve is to keep the air-bleed hole upwards in order to discharge the air in oil while testing the machines. The special instruction must be indicated before order if the valve will be installed vertically.

2.Air elimination: Please screw out the vent hole (when the system pressure set on 3Mpa) to eliminate the air, and screw the bolt tightly as soon as no air bubbles in the valve.

3. Manual regulation screw: When the electrical control system failure, the valve needs pressure supply temporarily, in this case, the manual regulation bolt should be screwed in at clockwise direction , but it should be back in normal operation.

4.Return pipe line: The back pressure should be as low as possible, keeping the end of return pipe line inserted under the oil surface directly. Trying to avoid pipe line twists or flow limited phenomena.

5.Maximum safe pressure set: The pressure setting should refer to the actual flow rate and pressure of pump, usually when the pump flow rate keeps under 100L/min., it can be set additional 1.5Mpa.
