8.2.3. rotating the actuator module
The actuator module (Remote Sensor and actuator) can
be rotated for straight seat valves and angle seat valves
belonging to series 2300, 2301 and 27xx only!
The position of the connections can be aligned steplessly by rotating
the actuator module (Remote Sensor and actuator) through 360°.
Only the entire actuator module can be rotated. The Remote
Sensor cannot be rotated contrary to the actuator.
The process valve must be in the open position for
alignment of the actuator module!
Danger!

• Before dismounting pneumatic lines and valves, turn off the
pressure and vent the lines.
