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 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.
Risk of personal injury due to exhaust air
being vented from pneumatically operated
components.
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.
7.1 Normal operation
The handwheel of valves with actuators tted
with an additional handwheel must be in the
neutral position during normal operation.
7.2 Manual operation
Valves with actuators tted with a handwheel
can be manually closed or opened in case of
supply air failure.
