For the manual operation of the valve. The
manual adjuster can either be attached di-
rectly to the valve or at the double adapter
instead of a control thermostat.

The Type 43-3 Regulator is not a safety
valve. If necessary, a suitable overpressure
protection must be installed on site in the
plant section.

Design and principle of operation

3.1 Additional fittings

Strainers
We recommend installing a SAMSON
strainer upstream of the valve in the flow
pipe. 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 1 NI) upstream
of the temperature regulator (u EB 1010).
Thermometer
Install a thermometer to monitor the tem-
perature prevailing in the plant.
Shut-off valves
We recommend installing a shut-off valve
both in the flow pipe and the return flow
pipe.
Insulation
Regulators and the pipeline can be insulated
to reduce heat energy transfer.
Refer to the instructions in the 'Installation'
section.
