Safety instructions and measures
WARNING
!
Risk of personal injury due to exhaust air being vented.
While the valve is operating, the pneumatic control valve (Type3222/2780) vents
during closed-loop control or when the valve opens or closes.
Î Install the control valve in such a way that vent openings 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.
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual process medium can escape and, depending on
its properties, may lead to personal injury, e.g. burns.
Î If possible, drain the process medium from all the plant sections affected and the
valve.
Î Wear protective clothing and safety gloves.
Risk of burn injuries due to hot components and pipelines.
Depending on the process medium, valve components and pipelines may get very hot
and cause burn injuries.
Î Allow components and pipelines to cool down.
Î Wear protective clothing and safety gloves.
Exposure to hazardous substances poses a serious risk to health.
Certain lubricants and cleaning agents are classied as hazardous substances. These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.
Î Make sure that an MSDS is available for any hazardous substance used. If neces-
sary, contact the manufacturer to obtain an MSDS.
Î Inform yourself about the hazardous substances and their correct handling.
