Technical Data - Samson 2417 Series Mounting And Operating Instructions

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 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 emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the regulator version, plant facilities and
process medium.
WARNING
!
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
Note
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
