Switch off operating
voltage:
Actuator closes with
spring (clockwise)
Signal on Y1
– rotation counter-
clockwise
– ball valve opens
Signal on Y2
– rotation clockwise
– ball valve closes

Flow = 0% at Y = 0 V
Flow = 100% at
Y = 10 V
See the mounting instructions M4658 for other switchings.
Emergency position
(Spring return)
On power failure or when the operating voltage is switched off,
the spring moves the ball valve to its mechanical zero position.
Position indication:
Mechanical
Rotary angle position indication with manual lever as position indicator.
Position indication:
Electrical
Output voltage U = DC
0...10 V is generated
proportional to the
rotary angle.
Manual adjustment – Without voltage supplied, the rotary actuator can be rotated and fixed in
any position using the supplied Allen key.
– The rotary actuator returns to the zero position (actuator closed) if me-
chanically unlocked via Allen key or via short-term voltage supply.
