Warning!
Spring tension in the valve
Danger of injury when detaching the clamp connection (43) as the released
spring pretension will suddenly lift the actuator.
► Therefore, release the spring tension before detaching the clamp
connections by pressurizing the actuator with compressed air at max. 8 bar.
Carry out the following steps:
1.
Remove the cleaning connection (30).
2.
Vent the valve at connection (L).
®
The valve discs (15/16) are raised.
3.
Remove the snap ring (43.1).
4.
Interrupt the compressed air supply to the connection (L).
5.
Pull off the control top (B) upwards.
®
Light-emitting diode A (green) will go out and light-emitting diode B will
flash yellow.
®
The valve insert has been removed.
