What’s The Solenoid Valve

Air solenoid valve, also known as an pneumatic solenoid valve, electrically-operated valve, or eletric air valve.

It’s a valve that uses solenoid component to open or close a orifice which the compressed air will get through. This is the basic process that opens the valve. Based on this unit, more complex air solenoid valve are designed.

The Work Principle

Take the directing action solenoid valve as a sample. The solenoid coil actuate the iron core directly to open or shut off the orifice. And the orifice is the channel which the medium with pass through. This type of solenoid valve is usually used for applications with small flow rates and operating pressures

The Advantage

Solenoid valves eliminate the need for manual or pneumatic control components in a pneumatic system. They only require an electrical input (and compressed air supply) to operate, this makes them easy to program and integration.So they are installed in a wide variety of applications.

What are the different types of air solenoid valve?

Air solenoid valve is the most important component of pneumatic control components, with a wide variety of specifications and different structures.

1. According to the control pattern, there are two types, direct-acting and pilot-acting.

2. According to the structure, there are three types: sliding column type, cut-off type and coaxial cut-off type.

3. According to the sealing form, there are two types of gap sealing and elastic sealing.

4. According to the power supply used, there are two types of DC and AC.

5. According to the use environment, there are ordinary type and explosion-proof type, etc.

6. According to the lubrication conditions, there are no oil lubrication needs and oil mist lubrication needed types.
