Page: 21 / 76

EB 2540 EN 3-3
Design and principle of operation
3.1 Additional fittings
Î
See Fig. 3-2
Pressure gauges
Install a pressure gauge (3) at suitable points
to monitor the pressures prevailing in the
storage tank.
Shut-off valves
We recommend installing a shut-off valve (1)
both upstream of the strainer.
Strainers
We recommend installing a SAMSON
strainer (2) upstream of the input pressure
regulator. It prevents solid particles in the
process medium from damaging the regula-
tor.
Î
Do not use the strainer to permanently
filter the process medium.
Î
Select a strainer (mesh size) suitable for
the process medium.
Any impurities carried along by the process
medium may impair the proper functioning
of the regulator. We recommend installing a
strainer (e.g. SAMSON Type 2 NI) upstream
of the input pressure regulator (
u
EB 1015).
