Structural principle of two position two way solenoid valve

The working principle of a two position two way solenoid valve is based on the principle of magnetic force and pressure balance. When the electromagnetic iron is energized, the magnetic field generated in the coil will cause the iron core to be subjected to electromagnetic force, causing the valve core to move upwards, thereby opening the valve and allowing liquid or gas to flow through the valve. When the electromagnet is powered off, the valve core will be moved downwards by the spring, causing the valve to close and preventing the flow of fluid. From this, it can be seen that the on-off control of the electromagnet controls the displacement of the valve core, thereby achieving on-off control of liquid or gas.
