Technical Data - Samson 42-36 E Mounting And Operating Instructions

Design and principle of operation
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 pressure reducing valve (u EB 1015).
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
Note
The Type 42-36 E Regulator is not a safety
valve. If necessary, a suitable overpressure
protection must be installed on site in the
plant section.

3.2 Technical data

The nameplates of the valve, actuator and
electric actuator provide information on the
valve and actuator versions (see the 'Mark-
ings on the device' section).
Note
More information is available in Data Sheet
u T 3018.
Conformity
The Type 42-36 E Regulator bears both the
CE and EAC marks of conformity.
Process medium and scope of application
The Type 42-36 E Pressure-independent
Control Valve (PICV) is designed to maintain
the flow rate in a plant to the adjusted set
point.
− Suitable for gases and liquids
− Max. temperature 150 °C
− Set points from 0.5 to 360 m³/h
− Valve size DN 15 to 250
− Pressure ratings from PN 16 to 40
The regulator is open when relieved of pres-
sure. The regulator closes when the flow rate
or the output signal of the electric controller
increases.
