Solenoid values are surprisingly complicated, and have a variety of tiny parts that make the value work properly. Solenoid Valves have a variety of different voltages for different uses, including 3 volts, 6 volts, 12 volts, and more. No matter the voltage, the valve works the same way to push water in and out of the valve for cooling or other uses. The internal parts of a 12 volt solenoid valve include:

Body: The body encases the rest of the parts and is typically made from water-resistant metal, such as stainless steel, or a coated metal.

Inlet port: This is the area of the valve where the water enters the valves. The water then moves inside the valve with the help of the other parts of the valve.

Solenoid: The solenoid is a tight coil that can twist to move the plunger up and down. When the solenoid moves up, the water comes into the valve. When it moves down, the water can exit the valve on the other side.

Coil windings: These windings help the coil stay in place and tighten and release without causing damage to the valve.

Lead wires: The wires help power the valve and keep it running electronically. Without electrical power, the valve could not work properly. The wires connect to the power unit of the machine.

Plunger: The plunger moves up and down controlled by the wires and the solenoid controlling the flow of the water in and out of the valve.

Orifice: This is the hole that the water uses to exit out of the valve after it moves through the solenoid unit.

Outlet port: The orifice flows into the outlet port, releasing the water from the solenoid.

All of these pieces work together to help the solenoid work in harmony. With a 12 volt solenoid valve, it is easy to control the flow of a liquid without using other complicated machinery to complete the task.
