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. We recommend installing a
strainer (e.g. SAMSON Type 1 NI) upstream
of the temperature regulator (
u
EB 1010).
Note
Thermometer
Install a thermometer (4) downstream of the
regulator to monitor the temperature prevail-
ing 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.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
