, and linear electric actuators are designed for actuation of shutoff and regulating valves. They transmit thrust to valve stem during its translational movement and they operate in industrial processes automated control systems according to command signals from regulating and controlling devices.

Electric actuator functions
  • Automatic, remote or manual opening and closing of valves, positioning of valve locking unit and its stopping in any intermediate position.
  • Indication of opening (closing) progress on a local position indication dial or on a display.
  • Formation of discrete signals of intermediate and limit positions of valve locking unit and of position analog signal.
  • Local and remote control of valve (electric actuators equipped with 1, 2, 3).
  • Adjustment and control of torque (thrust of linear actuators) within wide range.
  • Motor shutdown signal output when valve reaches limit positions (OPEN, CLOSED), upon reaching set torque on output shaft.
  • Protection from overtorque and jamming of valve movable parts (for actuators with torque limiter).
