What are the pneumatic valve fittings?

Several main accessories of pneumatic valve:

One: Solenoid valve

The exact name of solenoid valve should be electromagnetic reversing valve. There are two kinds of solenoid valves with pneumatic valves: two-position five-way valve and two-position three-way valve. Two-position five-way solenoid valve is usually used with double-acting pneumatic actuator, and two-position three-way solenoid valve is used with single-acting pneumatic actuator. The pneumatic valve switches the air inlet and air outlet of the air source through the energization or deenergization of the solenoid valve, so as to realize the opening and closing function of the valve. The solenoid valve has a single electric control solenoid valve and a double electric control solenoid valve. Flammable and explosive special occasions should use explosion-proof solenoid valves.

Two: limit switch

The limit switch is used to transmit the signal of valve opening or closing at a long distance, and the explosion-proof limit switch is used in flammable and explosive special occasions.

Three: Three-way gas source treatment

The gas source treatment triad includes a pressure reducer, a filter and an oil mist generator. The pressure reducer is mainly a stable air source and can adjust the cylinder pressure. The greater the pressure, the faster the valve will open and close, which will increase the friction of the valve and easily damage the sealing ring, thus affecting the service life of the valve. Filters and oil foggers can filter impurities in the air, clean and automatically add lubricant to the cylinder. Therefore, we suggest that users use the three-piece valve, which can better maintain the pneumatic actuator and have a longer service life.
