Start-Up; Start-Up And Putting The Device Back Into Operation - Samson 42-37 Mounting And Operating Instructions

6 Start-up

The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
WARNING
!
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
ries.
Allow components and pipelines to cool
down or warm up to the ambient tempera-
ture.
Î Wear protective clothing and safety
gloves.
WARNING
!
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Î Do not loosen the control line while the
valve is pressurized.
WARNING
!
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.
Î Wear hearing protection when working
near the valve.

DANGER
!
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
Before start-up or putting the valve back into
service, make sure the following conditions
are met:
− The regulator is properly installed into
the pipeline (see the 'Installation' sec-
tion).
− The leak and function tests have been
completed successfully (see the 'Testing
the regulator' section).
− The prevailing conditions in the plant
section concerned meet the regulator siz-
ing requirements (see information under
'Intended use' in the 'Safety instructions
and measures' section).
6.1 Start-up and putting the
device back into operation
1. Depending on the field of application,
allow the regulator to cool down or
warm up to reach ambient temperature
before start up.
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 regulator to ensure it functions
properly.
