Î See Fig. 3-3
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.
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 temperature regulator (u EB 1015).
Thermometer
Install a thermometer (3 and 5) at suitable
points to monitor the temperatures prevailing
in the plant.
Bypass and shut-off valves
We recommend installing a shut-off valve (1
and 6) both upstream of the strainer and
downstream of the regulator and installing a
bypass line. The bypass ensures that the
plant does not need to be shut down for ser-
vice and repair work on the regulator.
