Make sure that the pipeline and the compressed air lines are not under pressure.
Allow the pipeline and valves to cool down if a high tempreture system
Please follow the above to prevent injury.

4. Maintenance
4.2 Replacement of Disk Seal
Prior to assembly clean and grease the shaft and the contact surfaces together with the valve seal as per the lubrication
schedule in the annex.
A. Insert the long shaft of the disk into the bore of the seal.
B. Squash the seal and push over the short shaft of the flap in the direction of arrow A.
Proceed carefully. Avoid damage to the seal.
C. Place the disk into the seal as shown in the diagram.
4.3 Valve Assembly
The butterfly valve assembly is carried out in the reverse sequence.
- Align the rotary actuator with the buttefly valve (visual inspection). The actuator
shaft must be aligned with the valve disk.
- Tighten the screws equally.
- Connect the compressed air to the angled air connection of the rotary actuator
or control head.
- Connect the control line in accordance with the customer’s specifications (circuit diagram).
