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).
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.
The regulator is suitable for controlling
liq-
uids, gases or vapors
up to
350 °C
.
–
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 closed when relieved of
pressure. The valve
opens
when the
up-
stream
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 diaphram material (
u
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 and
process medium.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
The Type 41-73 Excess Pressure Valve is not
a safety valve. If necessary, a suitable over-
pressure protection must be installed on site
in the plant section.
Dimensions and weights
Table 5 provides a summary of the dimen
-
sions and weights. The lengths and heights
in the dimension diagrams are shown on
page 22 onwards.
