9.2.1 Prerequisites for Shutdown
Make sure that the following prerequisites are fulfilled before shutting down and
disassembling:
▪
The owner’s specifications for shutdown and disassembly are observed.
▪
The pipework and the ROTADISK Pneumatic Actuator are depressurised and free from

For shutting down, observe the information in the manufacturer’s documentation
(e.g. Ball Valve operating manual) of the automatic valve components.
1. Take the pipework out of operation.
2. Switch the valve (e.g. ball valve) several times so that fluid residues and
entrapped pressure can escape.
3. Make sure that there are no fluid residues or other substances in the pipework.
