Rotating the actuator

The position of the ports can be changed by turning the actuator
through 360°.
NOTE!
Damage to the seat seal and seat contour when valve
closed.
If the valve is closed when the actuator is turned, the seat seal
and the seat contour can be damaged.
• If the valve is closed: Before turning the actuator, open the
valve with the mechanical manual override. For a description
see "12.2 Actuating the valve mechanically".
→ For devices that have not been installed, clamp the valve body
in a holding device.
→ Place a suitable open-end wrench (width across flats M41)
on the hexagon head of the actuator.
→ Move the actuator into the required position by turning
it clockwise.
If only turning counterclockwise is technically possible for instal-
lation, observe the following safety warning:
WARNING!
Risk of injury from discharge of pressure and escaping
medium.
If the actuator is turned counterclockwise, the body connection
can loosen.
▶ When turning counterclockwise, hold the hexagon of the body
