Start-up
Before start-up or putting the valve back into
service, make sure the following conditions
are met:
−
The valve is properly installed into the
pipeline (see the 'Installation' section).
−
The leak and function tests have been
completed successfully (see 'Testing the
installed valve' in the 'Installation' sec
-
tion).
−
The prevailing conditions in the plant
section concerned meet the valve sizing
requirements (see information under 'In
-
tended use' in the 'Safety instructions
and measures' section).
Start-up/putting the valve back into opera
-
tion
1.
Allow the valve to cool down or warm up
to reach ambient temperature before
start-up when the ambient temperature
and process medium temperature differ
greatly or the medium properties require
such a measure.
2.
Slowly open the shut-off valves in the
pipeline. Slowly opening these valves
prevents a sudden surge in pressure and
high flow velocities which can damage
the valve.
3. Check the valve to ensure it functions
properly.
