The regulator does not require much mainte-
nance. Nevertheless, it is subject to natural
wear, particularly at the seat, plug and oper-
ating diaphragm. Depending on the operat-
ing conditions, check the regulator at regular
intervals to avoid possible malfunctions.
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equip -
ment. Improper opening can lead to device
components bursting.
− Before starting any work on the device, 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.
− If necessary, install a suitable overpressure
protection in the plant section.
− Wear personal protective equipment.
Risk of personal injury due to residual pro-
cess 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.
− 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.
Risk of regulator damage due to incorrect
servicing or repair.
Only allow trained staff to perform service
and repair work.
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques when tighten-
ing regulator components. Excessive tighten-
ing torques lead to parts wearing out more
quickly. Parts that are too loose may cause
leakage.
Observe the tightening torques specified in
section
9.2 .
