Features
● Brushless, robust DC motors ensure reliable operation regardless of load.
● The rotary 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 use with modulating controllers (DC 0/2...10 V), open-close or three-position
controllers.
● We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3-
point control to ensure continuous and accurate operation.

Rotary direction Clockwise (cw) or counter-clockwise (ccw) direction depends …
… on the type of control.
With no power applied, the actuator

switch
… on the positioning signal
The actuator remains in the achieved
position:
… if the control signal is maintained at a
constant value
… for loss of operating voltage.

NC (normally closed) ball valve NC (normally closed) ball valve
Basic setting:
Y1: Opening
Y2: Closing
DIL 3 set to “counter-clockwise”
Flow = 0% at Y = 0 V
Flow = 100% at Y = 10 V
NO (normally open) ball valve NO (normally open) ball valve
Basic setting:
Y1: Closing
Y2: Opening
DIL 3 set to “clockwise”
Flow = 100% at Y = 0 V
Flow = 0% at Y = 10 V
Combination with 6-port

Rotary direction “counter-clockwise” (ccw)
Y = 0 V Flow A ‒ C = 100% (0°)
Y = 5 V closed (45°)
Y = 10 V Flow B ‒ C = 100% (90°)
Rotary direction “clockwise” (cw)
Y = 0 V Flow B ‒ C = 100% (0°)
Y = 5 V closed (45°)
Y = 10 V Flow A ‒ C = 100% (90°)
