7 Maintenance
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. Op-
erators are responsible for drawing up an
inspection and test plan.
Details on faults and how to remedy them
can be found in Table 7.
We recommend removing the regulator from
the pipeline before performing any mainte-
nance or service work.
Tip
SAMSON's After-sales Service department
can support you in drawing up an inspection
and test plan for your plant.
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 be performed
by trained staff only.
