Pressure gauges
Install a pressure gauge at a suitable point to
monitor the pressures prevailing in the plant

Shut-off valves
We recommend installing a hand-operated
shut-off valve (1 and 6) both upstream and
downstream of the regulator.

Strainers
We recommend installing a SAMSON
strainer (2) upstream of the valve. It prevents
solid particles in the process medium from
damaging the regulator.
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. Therefore, we recommend
installing a strainer (e.g. SAMSON
Type 1 NI or 2 NI) upstream of the regulator
(

EB 1015).
