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the valve disc when the valve insert is withdrawn.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.

Danger of injury when detaching the clamp connection (43.1) as the
released spring pretension will suddenly lift the actuator.

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.
2.
