EB 8015 EN 5-13
Installation
Î Drain the process medium from the plant
sections affected as well as from the
valve.
Risk of personal injury due to pressurized
components and as a result of process me-
dium 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.
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, air is vented
from the actuator, e.g. during closed-loop
operation or when the valve opens or closes.
Î Wear eye protection when working in
close proximity to the control valve.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension. They can be identied by the long
bolts protruding from the bottom of the actu-
ator.
Î Before starting any work on the actuator,
relieve the compression from the pre-
loaded springs (see associated actuator
documentation).
To test the valve functioning before start-up
or putting back the valve into operation, per-
form the following tests:
