In recent years, explosion-proof electric actuator electric actuator has developed rapidly, and some domestic and foreign manufacturers have introduced intelligent electric actuator with fieldbus communication protocol. The new intelligent electric actuator integrates servo amplifier and actuator by means of computer and fieldbus communication technology. It not only realizes the functions of bidirectional communication, PID regulation, on-line automatic calibration, self-calibration and self-diagnosis, but also adds travel protection, over-moment protection and motor overheating. Protection, power failure signal protection, output field valve position indication and fault alarm functions. It can perform field operation or remote operation, complete manual operation and manual/automatic undisturbed switching.

Electric actuators are widely used in power plants, petroleum, steel, chemical industry, water treatment and other automatic control systems. Because of the advantages of advanced technology, high efficiency and stability, small size, large torque, precise wear resistance, safe use, economic and reasonable, it has become an ideal choice for the application of small and medium caliber valves in high frequency.

Main Characteristics of Electric Actuator

Cavity layout of motor, transmission and control elements, non-interference, space saving and easy maintenance

The transmission of multi-machine gear and turbine worm drive system is more smooth, stable and efficient.

Multiple protection functions such as overheating, overtorque and overlimit ensure safe operation of electric actuators

Excellent performance is based on careful selection of materials and rigorous testing of each component.

Optional switch type and adjustable type, which can accurately control the valve to keep in the correct position.

The design of three-phase amplifier adopts a combination scheme with single-phase intelligent servo amplifier and three-phase power converter, which facilitates production and material preparation, and makes it possible for the control room not to control three-phase power supply.
