Features
1.Simplify hydraulic system by breaking through the traditional complicated “one-pressure-one- controlling-valve” type of system.
2.Proportional coil can produce step-less pressure based on input electric current to bring out the best working condition of unifying hydraulic and electronic.
3.Function with fast response. The momentary number of pressure change is extremely small, hence is able to reduce the piping resonance.

Note: The resistance of the return pipe should be cut down by using only one pipe and directly insert into the oil tank.
Instructions
1.Installation: Users are advised to face the air-bleeder up.
2.Air Elimination: In order to stabilize the pressure, air in the pipe and valve should be eliminated completely. Please face the air-bleeder up, open up the screw to eliminate the air till there is no bubble (set up the pressure at 30kgf/cm2), then screw back in.
3.Manual Pressure Adjustment Screw: when the electric control breaks down and is in need of power supply, users can just manually spin the screw in.
Drain: Please directly insert the return lines underneath the tank to avoid the pipe from bending or resisting.
