Solenoid Valve is an air directional valve by using an electric coil to act with a spring or another electric coil when the valve is repositioned. A solenoid valve comprises an electromagnet that shuts and opens the valve when the switch is opened and closed. When the current flows through the solenoid, the resulting magnetic field sucks the valve pivot to open the valve. When the power cut-off switch is turned off, the pivot valve will return to its original position by their weight to close the valve

Solenoid valves can be divided into two types according to the valve movement characteristics: 1.Single Solenoid Valve and 2. Double Solenoid Valve

We can also classify them according to applications such as water solenoid valves, gas solenoid valves, hydraulic solenoid valves, and pneumatic solenoid valve.

A valve that controls the wind direction with a solenoid is an example of the pneumatic solenoid valve’s properties. There are many types to choose from such as 2/2, 3/2, 5/2 way and there are both N/O (Normal Open), N/C (Normal Close). They command together with a spring or another electric coil when needed. The valve is in another position by a 2-way type that is used for general air, gas, water, and oil applications.
