Special storage instructions for elastomers
Elastomer, e.g. actuator diaphragm
– To keep elastomers in shape and to pre-
vent cracking, do not bend them or hang
them up.
– We recommend a storage temperature of
15°Cforelastomers.
– Store elastomers away from lubricants,
chemicals, solutions and fuels.
SAMSON's After-sales Service department
can provide more detailed storage instruc-
tions on request.

5.1 Preparation for installation
Proceed as follows:
The plant operator is responsible for clean-
ing the pipelines in the plant.
Î Check the valve to make sure it is clean
and not damaged.
Î Flush and clean the pipeline thoroughly
before installing the regulator.
Any impurities carried along by the process
medium may impair the proper functioning
of the regulator. We recommend therefore
installing a strainer (e.g. SAMSON
Type2NI) upstream of the excess pressure
valve (see section5.4).
Î Check to make sure that the type desig-
nation,valvesize,material,pressurerat-
ing and temperature range of the valve
matchtheplantconditions(sizeand
pressure rating of the pipeline, medium
temperature etc.).
Î Check any mounted pressure gauges to
make sure they function.
