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.
