Single-turn electric actuators (, )

Main page      Electric actuators      Single-turn electric actuators (, )

, Single-turn (or part-turn) electric actuators , are designed for actuation of cutoff and regulating valves in industrial processes automated control systems in accordance with command signals from regulating and controlling devices.

Make 08, 09, 10, 11 and 12 explosion-proof electric actuators comply with requirements of 2-4.1-212-2008.

Functions of and actuators
  • Automatic, remote or manual opening and closing of valve, positioning of shutoff and regulating unit and its stopping in any required intermediate position.
  • Indication of valve opening (closing) progress on a local: mechanical indicator or display.
  • Formation of discrete signals of valve shutoff and regulating unit reaching intermediate and limit positions and of analog signals of this unit positions.
  • Local and remote control of valve (electric actuators equipped with 1, 2, 3).
  • Adjustment of torque within wide range.
  • Formation and transmission of motor shutdown signal upon reaching limit positions (OPEN, CLOSED) by valve shutoff and regulating unit, upon reaching the set torque value on actuator output shaft.
  • Overtorque protection from overload and jamming of valve movable parts.
