OPC solenoid valve 4WE6D62/EG220N9K4/V

The solenoid valve 4WE6D62/EG220N9K4/V is used in the liquid circuit system to achieve on/off of the liquid circuit or change the direction of the liquid flow. It generally has a valve core that can slide under the driving force of the coil electromagnetic force. When the valve core is in different positions, the path of the solenoid valve is also different.

When the two solenoid valve coils are energized, the balance hole circuit is closed, the relief hole circuit is opened, the upper chamber of the piston releases pressure, the piston rises, and the valve opens. On the contrary, the piston goes down and the valve closes. During the opening and closing process of the valve, the flow rate signal and valve plug position signal can be transmitted to the computer. After processing by the computer, corresponding instructions can be issued to control the on and off states of the two electromagnetic pilot valves, causing changes in the hydraulic pressure difference between the upper and lower chambers of the piston. From this, the piston can be controlled at the required opening height to achieve control of pipeline medium flow.
