The work described in this section is only to
be performed by personnel qualified for the
assignment accordingly.
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Valves and pipelines are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or the release of
compressed medium can cause serious in-
jury or even death.
Before working on the control valve:
Î
Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
Î
Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of electric shock.
Î
Do not remove any covers to perform
adjustment work on live parts.
Î
Before performing any work on the
device and before opening the device,
disconnect the supply voltage and protect
it against unintentional reconnection.
Î
Only use power interruption devices that
are protected against unintentional re-
connection of the power supply.
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 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
conditions. Additionally, a loud noise may
briefly occur through the sudden venting of
the pneumatic actuator or pneumatic valve
accessories not fitted with noise-reducing
fittings. 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 finger into the
yoke while the valve is in operation.
Î
Before working on the control valve,
disconnect and lock the pneumatic air
supply as well as the control signal.
Î
Disconnect the supply voltage before
performing any work on the control
valve.
