What Is Electric Actuator?

  • An electric actuator is a device that drives a valve to open and close by a motor. Electric actuators can be driven by electricity and signal sources, which means that electric actuators can be programmed to achieve remote control and realize industrial automation
  • Electric actuators are distinguished by stroke: Part turn electric actuator and multi turn electric actuator
  • Electric actuators are distinguished by function: Normal electric actuator, explosion-proof electric actuator and waterproof electric actuator
  • Electric actuators are distinguished according to the control method: ON/OFF type electric actuator, regulator type electric actuator and intelligent type electric actuator
  • Each electric actuator has its own function, if you have any confuse about selecting, feel free to consult us for more info.

Selection Guide Of Electric Actuator

  • Confirm the valve type
  • Confirm the valve size and connection size
  • Confirm the valve material including sealing material, disc material, ball material and valve body material
  • Confirm the size of the connection platform
  • Confirm the shaft is square or round and the size of it
  • Confirm the control methods and torque
  • Finally request a sample for testing

Or consult us and we will offer technical support online to help you select the right actuator.
