with the actuator face up.
• Before connecting the valve, ensure the pipelines are flush
(stress-free).
• Observe direction of flow!
See "Fig. 3".

8.3. Installation

8.3.1. Remove actuator from the valve
housing (for welded housings only)
WARNING!
Risk of injury from damaged devices!
If the wrong tools are used for assembly work, the device may be
damaged.
• To remove the actuator from the valve housing, use an open-end
wrench, never a pipe wrench.
Control function A:
→
Pressurize control air connection with compressed air (5.5 bar)
so that the pendulum disc is lifted off the valve seat and is not
damaged.
Control function B:
For control function B it is not necessary to apply compressed air for
installation.
NOTE!
Damage to the seat seal or the seat contour!
• When removing the actuator, ensure that the valve is in the open
position.
→
When valve is in open position, remove actuator from the valve
housing using an open-end wrench (see "Fig. 4").
