Measures for preparation
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 °C for elastomers.
−
Store elastomers away from lubricants,
chemicals, solutions and fuels.
SAMSON's After-sales Service can provide
more detailed storage instructions on re-
quest.
4.4 Preparation for installation
Proceed as follows:
Î
Flush the pipelines.
The plant operator is responsible for clean
-
ing the pipelines in the plant.
Î
Check the valve to make sure that it is
clean.
Î
Check the valve for damage.
Î
Check to make sure that the type desig-
nation, valve size, material, pressure rat-
ing and temperature range of the valve
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.).
Î
Check any mounted pressure gauges to
make sure they function.

5 Mounting and start-up
5.1 Mounting orientation
Standard mounting position
Î
Install the regulator in a horizontal pipe-
line with the set point adjuster (10) fac-
ing downward (see Fig. 1 and Fig. 2).
Installation conditions
−
Make sure that the regulator remains
freely accessible after the plant has been
completed.
−
Install a strainer upstream of the regula-
tor (see section 5.2).
−
The direction of flow must match the di
-
rection indicated by the arrow on the
body.
−
Connect external control lines at the side
of the main pipe (see Fig. 5)
−
Install the regulator free of stress.
Possible malfunction and damage due to ad
-
verse weather conditions (temperature, hu
-
midity).
−
Do not install the device outdoors or in
rooms prone to frost.
−
Protect the regulator against frost if it is
used to control freezing media.
−
Either heat the regulator or remove it from
the plant and completely drain the residual
medium.
