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.
SAMSON's After-sales Service can support
you in drawing up an inspection and test
plan for your plant.
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,
depressurize all plant sections affected as
well as the regulator.
−
Drain the process medium from all the
plant sections affected as well as the regu-
lator.
−
If necessary, a suitable overpressure pro-
tection must be installed on site in the plant
section.
−
Wear personal protective equipment.
Tip
DANGER
!
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 affected and the regu-
lator.
−
Wear protective clothing, safety gloves and
eye protection.
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 warm up to the ambient tempera-
ture.
−
Wear protective clothing and safety gloves.
Risk of regulator damage due to incorrect
servicing or repair.
Service and repair work must be performed
by trained staff only.
