Notice
The stem of the valve disc (15) is a sensitive component.
Damage to these parts can result in malfunction.
► The bearing disc (4) and the sealing disc (3) must not hit the stem (15) of
the valve disc when the valve insert is withdrawn.
► Do not place the valve insert down on the valve disc. Therefore lay down
the valve insert.

connections by pressurising the actuator with compressed air at max. 8 bar.
Carry out the following steps:
1.
Ventilate the valve.
®
The valve disc (15) is raised.
