8.4.2. rotation of the actuator module
The position of the connections can be aligned steplessly by rotating
the actuator module through 360°.
Only the entire actuator module can be rotated. The activation
unit cannot be rotated contrary to the actuator.
When aligning the connections, ensure that the valve is in
the open position.
procedure:
→
Clamp the valve housing in a holding device
(applies only to valves which have not yet been installed).
→
Counter on the flats of the nipple with a suitable open-end
wrench.
→
Fit special wrench* exactly into the wrench contour on the
underside of the actuator module.
Warning!
risk of injury from discharge of medium and pressure!
If the direction of rotation is incorrect, the interface between the
valve housing and nipple may become detached.
• To align the connections, rotate the actuator anti-clockwise only.
