Safety instructions and safety measures
WARNING !
Risk of personal injury due to sudden escape of process medium.
The valve has a safety bleed to detect damaged or worn O-rings. The process medium
may escape suddenly and at high pressure.
Î
Wear protective clothing, gloves and eyewear when working near or on the valve.
Î
Do not stay in the range of the safety bleed longer than necessary.
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.
Risk of personal injury due to preloaded springs.
Valves in combination with pneumatic actuators with preloaded springs are under ten-
sion. These control valves with SAMSON pneumatic actuators can be identified by the
long bolts protruding from the bottom of the actuator.
Î
Before starting any work on the actuator, relieve the compression from the preloaded
springs (see associated actuator documentation).
