Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER !
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equipment. Impermissible pressure or improper
opening can lead to valve components bursting.
Î
Observe the maximum permissible pressure for valve and plant.
Î
Before starting any work on the control valve, depressurize all plant sections affect-
ed as well as the valve.
Î
Drain the process medium from all the plant sections concerned as well as the
valve.
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.
