6 Start-up
The work described in this section is only to
be performed by personnel appropriately
qualied 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 heat up.
Î Wear protective clothing and safety
gloves.
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Î Do not loosen the screw of the test con-
nection while the valve is pressurized.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or ashing)
may occur during operation caused by the
process medium and the operating
conditions. Additionally, a brief loud noise
may occur through the sudden venting of the
pneumatic actuator (see 'Fail-safe position')
or pneumatic valve accessories not tted with
noise-reducing ttings. Both can damage
hearing.
Î Wear hearing protection when working
near the valve.
Crush hazard arising from actuator and
plug stem moving.
Î Do not insert hands or nger into the
yoke while the air supply is connected to
the actuator.
Î Before working on the control valve, dis-
connect and lock the pneumatic air sup-
ply as well as the control signal.
Î Do not impede the movement of the actu-
ator and plug stem by inserting objects
into the yoke.
Î Before unblocking the actuator and plug
stem after they have become blocked
(e.g. due to seizing up after remaining in
the same position for a long time), re-
lease any stored energy in the actuator
(e.g. spring compression). See associat-
ed actuator documentation.
Risk of personal injury due to exhaust air
being vented.
While the valve is operating, the actuator,
for example, may vent during closed-loop
operation or when the valve opens or closes.
Î Wear eye protection when working in
close proximity to the control valve.
