Features
 


  • Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and moves to the position defined by the control signal. The measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.
  • Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.
  • Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).

  • Simple direct mounting Straightforward direct mounting on the ball valve with only one screw. The mounting position in relation to the ball valve can be selected in 90°<) steps.

  • High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when theend stop is reached.

  • Position feedback U5 Operation of the ball valve is optimised by a limiting ring. This ring reduces the angle of rotation from 95° to 90° , i.e. U5 will deviate from Y by approximately 0.3 V when the valve is closed.

  • Home position When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the «gear disengagement» switch, the actuator moves to the home position.
    The actuator then moves into the position defined by the control signal.
