Design and principle of operation
3.1 Technical data
The valve and actuator nameplates provide
information on the valve and actuator ver-
sions (see section 2.1).
Process medium and scope of application
The Type 41-23 Pressure Reducing Valve is
used to maintain the pressure downstream of
the regulator to an adjusted set point.
−
For
liquids, gases or vapors
−
Max. temperature
350 °C
−
Set points from
0.05 to 28 bar
−
Valve size
DN 15 to 100
−
Pressure ratings from
PN 16 to 40
The regulator is open when relieved of pres-
sure. The valve
closes
when the
downstream
pressure rises.
Temperature range
Depending on how the regulator is config
-
ured, it can be used up to temperatures of
350 °C (Table 1). The minimum temperature
is limited by the accessories used and the ac-
tuator's diaphragm material (

Leakage class
The metal-seated regulator has the leakage
class I according to IEC 60534-4.
The soft-seated regulator has the leakage
class IV according to IEC 60534-4.
Noise emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the regulator version, plant facilities, process
medium and operating conditions.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
The Type 41-23 Pressure Reducing Valve is
not a safety valve. If necessary, a suitable
overpressure protection must be installed on
site in the plant section.
