Samson EB 8015 EN User Manual

EB 8015 EN 7-1
Operation
7 Operation
Immediately after completing start-up or put-
ting the valve back into operation, the valve
is ready for use.
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 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 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
conditions. Additionally, a loud noise may
briey occur through the sudden venting of
the pneumatic actuator 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,
disconnect and lock the pneumatic air
supply as well as the control signal.
Î Do not impede the movement of the
actuator 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.
