The current is supplied to the solenoid valve from these wires. Externally this coil is covered with the steel covering and inside the hollow part there is a plunger or the piston, whose motion inside the hollow space is controlled by the spring.Ħ) Lead wires: These are external connections of the solenoid valve that are connected to the electrical supply. The coil forms the shape of the hollow cylinder. Inside the solenoid valve there is solenoid coil.ĥ) Coil windings: The solenoid consists of several turns of the enameled wire wound around the ferromagnetic material like steel or iron. The body is covered with steel covering and it has metallic finish.

The body of the solenoid coil is cylindrical in shape, and it is hollow from inside.

The outlet port is eventually connected to the process where the fluid is required.Ĥ) Coil/ Solenoid: This is body of the solenoid coil. The solenoid valve controls the flow of the fluid from inlet port to the outlet port. Ordinarily the flow from the valve is controlled by the handle, but in case of the automatic valve the solenoid valve is connected to the valve.Ģ) Inlet port of the valve: This is the port through which the fluid enters inside the automatic valve and from here it can enter into the final process.ģ) Outlet port: The fluid that is allowed to pass through the automatic valve leaves the valve through the outlet port. The valve is usually connected in the process flow pipeline to control the flow of certain fluid like liquid or air. Here are the various parts of the solenoid valve and their working (please refer the figure above).ġ) Valve body: This is the body of the valve to which the solenoid valve is connected. Solenoid Valve Parts of the Solenoid Valve and their Working The parts of the typical solenoid valve are shown in the figure below and described below. Let us now see the parts of the solenoid, which will also help us understand the working of the solenoid valve.
