tor, depressurize plant sections as well as
the regulator.
WARNING WARNING
! !
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.
To decommission the regulator for service
work or disassembly, proceed as follows:
1. Close the shut-off valve (1) on the up-
stream side of the regulator.
2. Close the shut-off valve (6) on the down-
stream side of the regulator.
3. Depressurize the plant.
4. Completely drain the pipelines and
valve.
5. If necessary, allow the pipeline and reg-
ulator components to cool down or warm
up to the ambient temperature.
