Background

The actuator is an essential important component of an automatic control system. It is used to receive the control signal from the controller and change the size of the controlled medium to maintain the controlled variable at the required value or in certain range. The actuators can be classified into pneumatic, hydraulic and electric according to their energy forms. The pneumatic actuator uses compressed air as energy source, and features simple structure, reliable and stable action, large output thrust, convenient maintenance, fire and explosion prevention and low cost, so that it may be used widely in chemical, paper making, oil refining and other production processes. Even when using an electric gauge or computer control, the pneumatic actuator may still be used as long as the electrical signal is converted to a standard pneumatic signal of 20-100kPa via an electro-pneumatic transducer or an electro-pneumatic valve positioner. The electric actuator has the advantages of convenient energy source taking, rapid signal transmission, complex structure and poor explosion-proof performance. The hydraulic actuator is basically not used in the production processes of chemical engineering, oil refining and the like, and is characterized by very large output thrust.
