Start-up
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Valve components and the pipeline may be-
come very hot or cold. Risk of burn injuries.
Î
Allow components and pipelines to cool
down or warm up to the ambient tem
-
perature.
Î
Wear protective clothing and safety
gloves.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the
process medium and the operating condi
-
tions. Additionally, a loud noise may briefly
occur through the sudden venting of the
pneumatic actuator or pneumatic valve ac
-
cessories not fitted with noise-reducing fit
-
tings. Both can damage hearing.
Î
Wear hearing protection when working
near the valve.
Risk of personal injury due to exhaust air
being vented.
While the valve is operating, air is vented
from the actuator, for example, during
closed-loop operation or when the valve
opens or closes.
Î
Wear eye protection when working in
close proximity to the control valve.
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).
