Safety instructions and measures
WARNING
!
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. (chemical) burns.
Î
If possible, drain the process medium from all the plant sections concerned and the
valve.
Î
Wear protective clothing, gloves, and eyewear.
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 gloves.
1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the electric control valve due to the power supply exceeding the
permissible tolerances.
The electric control valves are designed for use according to regulations for low-voltage
installations.
Î
Observe the permissible tolerances of the power supply. See associated actuator
documentation.
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant engineering company is responsible for cleaning the pipelines in the plant.
Î
Flush the pipelines before start-up.
Î
Observe the maximum permissible pressure for valve and plant.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for a process medium with defined properties.
Î
Only use the process medium specified for sizing the valve.
