Working principle of hydraulic solenoid valve

Bosch Rexroth 4WE10 hydraulic solenoid valve is a kind of automatic basic components which used to control the flow, belonging to the actuator.Directional hydraulic control valve used to control the direction of hydraulic flow, the plant’s mechanical devices are generally controlled by hydraulic cylinder, so it will be used in directional hydraulic control valve.
The Bosch Rexroth 4WE10 hydraulic solenoid valve has a closed cavity, in which the different position of the hole, each hole connecting different tubing.The middle of the cavity is the piston, the two sides are two magnets, which the magnet coil on the body will be attracted to the side, through the directional hydraulic valve to open or close the directional hydraulic control valve to open different oil drain hole.And into the hole is open, the hydraulic oil will enter a different row of tubing, and then through the pressure to promote the piston, the piston and the piston rod, the piston rod drives the mechanical device.Thus through the current control of an electromagnet to control the mechanical movement.
