Installation
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.
