The work described in this section is only to
be performed by personnel qualified for the
assignment accordingly.
Valve and electric actuator can be assem-
bled before or after the valve has been in-
stalled in the pipeline. We recommend first
installing the valve without the electric actua-
tor into the pipeline.
5.1
Preparation for installation
Valve and actuator can be assembled before
or after the valve has been installed in the
pipeline. We recommend first installing the
valve without the actuator into the pipeline.
Before installation, make sure the following
conditions are met:
−
The valve is clean.
−
The valve, actuator and all piping are
not damaged.
−
Install a strainer upstream of the regula-
tor.
−
The valve data on the nameplate (type
designation, valve size, material, pres
-
sure rating and temperature range)
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.). For more details on the
nameplate, see section 2.1.
−
The requested or required additional
pipe fittings (see section 5.3) have been
installed or prepared as necessary be-
fore installing the valve.
Proceed as follows:
Î
Lay out the necessary material and tools
to have them ready during installation
work.
Î
Flush the pipeline
before
installing the
regulator (see section 6.1).
The plant operator is responsible for
cleaning the pipelines in the plant.
Î
Check any mounted pressure gauges to
make sure they function properly.
The plant operator is responsible for clean-
ing the pipelines in the plant.
Any impurities carried along by the process
medium may impair the proper functioning
of the regulator. Therefore, we recommend
installing a strainer (e.g. SAMSON
Type 1 NI) upstream of the regulator. See
section 5.3.
