Servicing
9 Servicing
The work described in this chapter is to be
performed only by personnel appropriately
qualied to carry out such tasks.
The following documents are also required
for servicing the valve:
− Mounting and operating instructions for
the mounted actuator, e.g. uEB8310-X
for Type3271 or Type3277 Pneumatic
Actuator
− uAB0100 for tools, tightening torques
and lubricant
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
process medium under pressure can cause
serious injury 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 the plant
sections affected as well as from the
valve.
Risk of burn injuries due to hot or cold
components 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 personal injury due to pressurized
components and as a result of process
medium being discharged.
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 condi-
tions. Additionally, a loud noise may briey
occur through the sudden venting of the
pneumatic actuator or pneumatic valve ac-
cessories not tted with noise-reducing t-
tings. 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.
