What Is Industrial Electric Valve Actuators?

  • 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.

Applications Of Electric Actuators

covnaactuator-rotary-electric-actuators-manufacturers

Normally, the actuator works with valves. Like ball valve, butterfly valve, gate valve or globe valve. Actuator valves are very important for fluid control for various applications. They are widely used in the following industries.

  • Water treatment
  • Paper and pulp
  • Food and beverage
  • Shipbuilding
  • Irrigation
  • Chemical processing
  • Sugar

Selection Guide Of Electric Actuator

  • Confirm the valve type
  • Confirm the valve size and connection size
  • 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 help you to select the right actuator to meet your actuation needs
