1. Use appropriate protective gear as
specifi ed in plant operator's guidelines.
2. Shut off plant or plant component.
3. Secure against recommissioning.
4. Depressurize the plant or plant
component.
The operator must carry out regular visual
examination of the valves dependent on
the operating conditions and the potential
danger in order to prevent leakage
and damage. The valve also has to be
disassembled in corresponding intervals
and checked for wear (see chapter 12
"Assembly / disassembly of spare parts").
Important:
Service and maintenance: Seals
degrade in the course of time. After
valve disassembly / assembly
check that the hexagon nuts a are
tight and retighten as necessary.
