- 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. The measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.
- Flow characteristic An equal-percentage flow characteristic is produced by profiling the valve cone.
- Manual override Manual override with pushbutton possible (the gear is disengaged for as long as the button is pressed or remains locked).
