Regulator Type Electric Actuator

Modulating type electric actuator also is a 90-degree rotary actuator. It has an adjustable switch angle from 0 degrees to 90 degrees. It could help you to regulate the switch angle therefore helping you to control the flow rate easier.

It could receive a signal to help to regulate the switch angle and feedback the signal to help to check the valve positioner.

Offering the best solution to help to control remotely and automated.

Adjustment Rotation: 0 degrees to 90 degrees

Torque Range: 50Nm to 4,000Nm

Voltage: DC12V, DC24V, AC24V, AC110V, AC220V, AC380V

Open/Close Time: 8S to 90S

Protection Class: IP65 or IP67

Other Options: Manual override is accepted

Input / Output Signals: 4-20mA, 0-10VDC, 1-5VDC

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

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
