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.
Pressure gauges
Install a pressure gauge at a suitable point to
monitor the pressures prevailing in the plant
(3 and 5).
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 excess pressure valve (
u
EB 1015) .
Shut-off valves
We recommend installing a shut-off valve (1
and 6) both upstream of the strainer and
downstream of the regulator. The shut-off
valves ensure that the entire plant does not
need to be shut down for service and repair
work on the regulator.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
