Features
● Brushless, robust DC motors for reliable operation regardless of load.
● The valve actuators do not require an end position switch, are overload proof, and
remain in place upon reaching the end stop.
● The gears are maintenance free and low noise.
● Suitable for operating with the Intelligent Valve Controller.

Flow = 0% at Y = 0 V
Flow = 100% at Y = 10 V
The actuator remains in the deployed position:
…if the positioning signal is maintained at a constant value.
…in the event of a power loss.
Position indication, mechanical Rotary angle position indication via position indicator/manual lever.
Position indication, electrical Position indicator: Output voltage U = DC 0…10 V is generated proportional to
rotary angle.
The direction of action (inverted or non-inverted) for output voltage U is based
on the DIL switch position.
The rotary angle range is self-
adapting
If self-adaptation is enabled, the actuator automatically determines the
mechanical end stops of the rotary angle.
Manual adjustment The actuator can be manually adjusted by pressing the gear train
disengagement button.
Rotary angle limitation A set screw can limit the rotary angle to between 0° and 90°.
CAUTION
Adjusting DIL switch 1 prevents the complete closure of the valve.
The remaining flow can result in a loss of comfort or property damage caused by the
overheating of the piping system.
● DIL switch 1 must remain at factory setting '0…10 V'.
CAUTION
Adjusting DIL switch 3 may result in the complete opening of the control valve.
Excessive flows may result in property damage due to overheating of the piping system,
damage to the flow sensor on the Intelligent Valve, or damage to the plant.
● DIL switch 3 must remain at factory setting 'Counter-clockwise'.
