Working principle of electro hydraulic control valves

Electro hydraulic reversing valve and hydraulic control valves are used in the hydraulic system which the flow over the normal operation of the solenoid hydraulic control valves to control the movement of the actuator or control the flow direction of the oil.

Notice of the electro yuken hydraulic valves

1.Products can be arbitrarily installed, priority level position.

2.The hydraulic system must be filtered by the media, filtration accuracy at least 20μm.

3.Fixed screw selection according to the parameters listed in the sample.

4.The roughness of the surface of the hydraulic control valve is required to Ra0.8, and the flatness is required for 0.01/100mm.

Working principle

When the two yuken hydraulic valves coil through the power, the balance hole circuit is closed, the discharge hole circuit is opened, the piston pressure relief, the piston upward, the valve opens. On the contrary, the piston down, the valve closes. In the yuken hydraulic solenoid valve opening and closing process, the flow rate signal and valve plug position signal is transmitted to the computer, after the computer processing to send out the corresponding command, control power down state of the two solenoid hydraulic control valves, so that the piston of the upper chamber of the hydraulic pressure difference, so that the piston control in the required opening height, to achieve the pipeline medium flow control.
