What are the common accessories for pneumatic valves?

In recent years, pneumatic valves have the advantages of fast switching and low price, and have a certain market share. However, only by mastering the use and characteristics of related accessories can they achieve stable performance and long service life in use. We believe that in addition to improving the valve quality of the pneumatic valve and the matching of accessories are also very important. Below we introduce the characteristics and uses of several main accessories of pneumatic valves.

 

 

Accessory 1: Solenoid valve

The exact name of the solenoid valve should be the solenoid directional valve. The solenoid valve equipped with pneumatic valve mainly has two five-way and two-way three-way. Two-position five-way solenoid valve is usually used in conjunction with a double-acting pneumatic actuator, and two-position three-way solenoid valve is used in conjunction with a single-acting pneumatic actuator.

 

Pneumatic valves are used to switch the air inlet and outlet of the air source through the switch of the solenoid valve to achieve the function of opening and closing the valve. The solenoid valve has a single electronic control solenoid valve and a double electronic control solenoid valve. Explosion-proof solenoid valves should be used in special flammable and explosive occasions.

 

 

Accessory 2: Limit switch

The limit switch is a long-distance transmission signal to open or close the valve. The explosion-proof limit switch should be used in special flammable and explosive occasions.

 

 

Accessories 3: Air source treatment triple

The air source treatment triple includes a pressure reducer, a filter, and an oil mist device. The pressure reducer is mainly used to stabilize the air source and can adjust the pressure of the valve cylinder. The greater the pressure, the faster the valve opening and closing speed, which increases the friction of the valve and easily damages the sealing ring, thus affecting the service life of the valve;

 

Filters and lubricators can filter impurities in the air, clean and automatically add lubricant to the cylinder. Therefore, we recommend that users match a valve with a triple piece, so that the pneumatic actuator can be better maintained and used for a longer time.

 

 

Accessories 4: Actuator

Actuators often work under high temperature, high pressure, deep cold, strong corrosion, high viscosity, easy crystallization, flashing, cavitation, high pressure difference, etc. In the process control system, the actuator receives the command signal from the regulator and converts it into the corresponding angular displacement or linear displacement by the actuator to manipulate the adjustment mechanism and change the energy or material that the controlled object enters and exits to realize the process automatic control.

 

In any automatic control system, the electric linear actuator is an indispensable part. If the sensor is compared to the sensory organ of the control system, the regulator is the brain of the control system, and the actuator can be compared to the hand that does a specific job.
