7 Servicing

The regulator does not require any 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.

DANGER
!
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 concerned as
well as the valve.
− Drain the process medium from all the
plant sections concerned as well as the
valve.
− If necessary, install a suitable overpressure
protection in the plant section.
− Wear personal protective equipment.
WARNING
!
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.
(chemical) burns.
EB 3136 EN
− If possible, drain the process medium from
all the plant sections concerned and the
valve.
− Wear protective clothing, safety gloves and
eyewear.
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 heat up.
− Wear protective clothing and safety gloves.
NOTICE
!
Risk of regulator damage due to incorrect
servicing or repair.
Service and repair work must only be per-
formed by trained staff.
NOTICE
!
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the tightening torques specified in
Fig. 2.
