The regulators do not require any mainte-
nance. Nevertheless, they are subject to nat-
ural wear, particularly at the seat, plug and
operating diaphragm.
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equip -
ment. Improper opening can lead to valve
components bursting.
− Before starting any work on the valve, de -
pressurize all plant sections affected as
well as the valve.
− Drain the process medium from all the
plant sections affected as well as the valve.
− Wear personal protective equipment.
Risk of personal injury due to residual
process medium in the valve.
While working on the valve, residual me -
dium can flow out of the valve and, depend -
ing on its properties, cause personal injury,
e.g. (chemical) burns.
− If possible, drain the process medium from
all the plant sections affected and the
valve.
− Wear protective clothing, safety gloves and
eye protection.
DANGER !
WARNING !
Risk of burn injuries due to hot or cold com-
ponents and pipelines.
Depending on the process medium, valve
components and pipelines may get very hot
or cold and cause burn injuries.
− Allow components and pipelines to cool
down or warm up to the ambient tempera -
ture.
− Wear protective clothing and safety gloves.
