Disassembly
For disassembly, the following principles apply:
• Only allow qualified staff to disassemble the valve.

being switched back on. Work may only be started once any residual energy has
been discharged.
• Disconnect all power and utility lines.
• Markings, e.g. on lines, must not be removed.
• Do not climb on the valve. Use suitable access aids and working platforms.
• Mark the lines (if unmarked) prior to disassembly to ensure they are not confused
when re-assembling.
• Protect open line ends with blind plugs against ingress of dirt.
• Pack sensitive parts separately.
• For longer periods of standstill, observe the storage conditions, see Storage
(page 21).
