Features
 

• Mode of operation The actuator is controlled by means of a standard control signal DC 0 ... 10 V. It opens to the position dictated by this signal. The measuring voltage U allows the ball position (0 ... 100%) to be electrically indicated and serves as a follow-up control signal for other actuators.


• Simple direct mounting Straightforward direct mounting on the ball valve with only one screw. The assembly tool is integrated in the plug-on position indicator. The mounting position in relation to the ball valve can be selected in 90° steps.


• Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).


• Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.


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


• 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.
  Factory setting: Y2 (counter-clockwise rotation)
  The actuator then moves into the position defined by the control signal.
