Features

• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the position defined by the control signal. Measuring voltage U serves for the electrical display of the actuator position 0 ... 100% and as slave control signal for other actuators.


• Simple direct mounting Simple direct mounting on a butterfly valve with ISO 5211-F05 mounting flange. The mounting position in relation to the butterfly 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.
