1.2 Notes on possible personal injury

WARNING
!
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, valve components and pipelines may get very hot
or cold and cause 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.
The noise emissions depend on the valve version, plant facilities and process medium.
Î Wear hearing protection when working near the valve.
Risk of personal injury due to exhaust air being vented.
While the valve is operating, the actuator, for example, may vent during closed-loop
operation or when the valve opens or closes.
Î Install the control valve in such a way that vent holes are not located at eye level and
the actuator does not vent at eye level in the work position.
Î Use suitable silencers and vent plugs.
Î Wear eye protection when working in close proximity to the control valve.
Crush hazard arising from moving parts.
The control valve contains moving parts (actuator and plug stem), which can injure
hands or fingers if inserted into the valve.
Î Do not insert hands or finger 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), release any
stored energy in the actuator (e.g. spring compression). See associated actuator
documentation.
