7.4. rotating the actuator module
The actuator module (Pneumatic Control Unit and actuator)
can be rotated for straight seat valves and angle seat valves
only!
The position of the connections can be aligned steplessly by rotating the
actuator module (Pneumatic Control Unit and actuator) through 360°.
Only the entire actuator module can be rotated. The Pneu-
matic Control Unit cannot be rotated contrary to the actuator.
The process valve must be in the open position for alignment
of the actuator module!
DangEr!
risk of injury from high pressure!
• Before dismounting lines and valves, turn off the pressure and
vent the lines.
procedure:
→
Clamp valve body in a holding device (only required if the process
valve has not yet been installed).
→
Control function A: Open process valve.
