Features
 

• 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 stop. 


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