Additional Fittings - Samson 42-10 Mounting And Operating Instructions

Design and principle of operation

3.1 Additional fittings

Î See Fig. 3-3
Pressure gauges
Install a pressure gauge (3 and 5) at suitable
points to monitor the pressures prevailing in
the plant.
Shut-off valves
We recommend installing a shut-off valve (1
and 6) both upstream of the strainer and
downstream of the regulator.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.

Strainer
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.
Note
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 pressure reducing valve (u EB 1015).
