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.
Plant operators are responsible for drawing
up an inspection and test plan. Details on
faults and how to remedy them can be found
in the 'Malfunctions' section.
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
We recommend removing the regulator from
the pipeline before performing any mainte-
nance or service work.
Danger due to suspended loads falling.
Î
Stay clear of suspended or moving
loads.
Î
Close off and secure the transport paths.
Risk of personal injury due to the regulator
tipping.
Î
Observe the regulator's center of gravity.
Î
Secure the regulator against tipping over
or turning.
DANGER
!
WARNING
!
Risk of burn injuries due to hot or cold
components and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju
-
ries.
Î
Allow components and pipelines to cool
down or warm up to the ambient tem
-
perature.
Î
Wear protective clothing and safety
gloves.
Risk of personal injury due to residual
process 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.
Î
Wear protective clothing, safety gloves
and eye protection.
Risk of lifting equipment tipping over and
risk of damage to lifting accessories due to
exceeding the rated lifting capacity.
Î
Only use approved lifting equipment and
accessories whose minimum lifting ca
-
pacity is higher than the weight of the
valve (including actuator and packaging,
if applicable).
Î
Refer to the 'Design and principle of op
