Structural principle of two position four way solenoid valve

Two position four way solenoid valve, when the electromagnetic iron is energized, a magnetic field is generated to attract the iron core, and at the same time, the pin connecting the valve core is pulled upwards. When the valve core moves upwards, the sealing surface between the guide hole and the valve body detaches, and the medium can flow along the flow channel; On the contrary, when the electromagnet loses power, the iron core loses its suction force, the valve core is pressed back to its original position by the spring, the sealing surface forms a seal again, and the medium flow is cut off.
