1.2 installation of the process valve
Thread type and dimensions can be found in the corresponding data sheet.
Connect the valve according to the operating instructions for the valve. →
2 ROTATING THE ACTUATOR MODULE
The actuator module cannot be rotated unless there are straight seat and slanted seat valves!
Following installation of the process valve, if the positioner display is only partially visible or the connection cables or hoses cannot
be fitted properly, the actuator module (positioner and actuator) can be rotated into a position suitable for the connection.
Only the entire actuator module can be rotated. The positioner cannot be rotated contrary to the actuator.
Procedure:
Clamp the valve housing in a retaining jig (only possible if the process valve has not yet been installed).
→
Using a suitable open-end wrench, counter the wrench flat on the pipe. →
Fit special key* exactly into the key contour on the underside of the actuator module. →
WARNING!
Risk of injury from discharge of medium and pressure!
If the direction of rotation is wrong, the housing interface may become detached.
Do not rotate the actuator module in a clockwise direction!
Rotate the actuator module
→ in an anti-clockwise direction into a position suitable for the pneumatic connection.
* The special key is available from your Bürkert sales office.
