Design and principle of operation
Noise emissions
Trims with flow dividers can be used to re -
duce noise emission (
u
T 2517).
The Type 41-73 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 valve and actuator nameplates provide
information on the valve and actuator ver-
sions (see the 'Markings on the device' sec-
tion).
More information is available in Data Sheet
u
T 2517.
Process medium and scope of application
The Type 41-73 Excess Pressure Valve is
used to maintain the pressure upstream of
the regulator to an adjusted set point.
− For liquids, gases and 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 closed when relieved of
pressure. The valve
opens when the up-
stream pressure rises.
Note
Note
Compliance
The Type 41-73 Regulator bears both the CE
and EAC marks of conformity.
Temperature range
Depending on how the regulator is config -
ured, it can be used up to temperatures of
350 °C (see Table 3-1). The minimum tem -
perature is limited by the accessories used
and the actuator's diaphragm material
(
u
T 2595).
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 emissions
SAMSON is unable to make general state-
ments about noise emissions. The noise emis-
sions depend on the regulator version, plant
facilities, process medium and operating
conditions.
Dimensions and weights
Table 3-5 provides a summary of the dimen-
sions and weights. The lengths and heights
in the dimensional drawings are shown on
page 3-10.
