Description

Welcome to purchase discount source pneumatic actuator single acting and double acting valve pneumatic actuator from our company, which is one of the best China pneumatic actuator single acting and double acting valve pneumatic actuator manufacturers and suppliers.

The definition of pneumatic actuator 

Pneumatic actuator is an actuating device for opening and closing or regulating valve by gas pressure. The application temperature range of pneumatic actuator is -60 ~+130. Pneumatic actuator is widely used in power plant, chemical industry, oil refining and so on. There are single acting pneumatic actuator and double acting pneumatic actuator.

 

Single acting pneumatic actuator & double acting pneumatic actuator

Single action pneumatic actuator: the movement of the cylinder is achieved by the air pressure of the instrument and it returned by the pressure provided of spring.

Double action pneumatic actuator: the movement and the return of the cylinder are achieved by the air of the instrument.

The single acting torque is much smaller than the double acting. Therefore, the double action pneumatic actuator is generally applied in valves that need larger torque.

 

The advantages of pneumatic actuator mainly include the following 4 aspects:

(1) Large load: Pneumatic actuator can be adapted to the application of high torque output.

(2) Quick action and fast reaction. The pneumatic actuator can achieve the required pressure and speed in a relatively short time.

(3) Good adaptability to working environment, especially in the flammable, explosive, multi dust, strong magnetic, radiation and vibration and other harsh working environment, the pneumatic actuator is superior than the hydraulic, electronic, electrical control.

 

The application of pneumatic actuator

Pneumatic actuator can simply achieve rapid linear cycle movement. With simple structure and easy maintenance, pneumatic actuator can also be used in a variety of harsh working environment, such as explosion-proof requirements conditions, multi dust or wet conditions. Pneumatic actuator is more suitable for simple motion control.

 

How to choose the pneumatic actuator?

When the maximum closing pressure is large, the cost of using the single acting actuator is very high. On this condition, A double acting pneumatic actuator is a better option as it is more cost saving. 

If there are security requirements, usually, a single acting pneumatic actuator is prefered; if there is a positioning requirement, the double acting pneumatic actuator is a better one.
