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.
Regulators 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 regulator.
− Drain the process medium from all the
plant sections concerned as well as the
regulator.
− If necessary, a suitable overpressure pro-
tection must be installed on site in the plant
section.
− Wear personal protective equipment.

WARNING
!
Risk of personal injury due to residual pro-
cess medium in the regulator.
While working on the regulator, residual
process medium can escape and, depending
on its properties, may lead to personal in-
jury, e.g. (chemical) burns.
− If possible, drain the process medium from
all the plant sections concerned and the
regulator.
− 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, regula-
tor 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.
