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 2405 Pressure Reducing Valve is
used to maintain the pressure downstream of
the valve to an adjusted set point.
− For gases
− Temperature range –20 to +60 °C
− Set points from 5 mbar to 10 bar
− Valve size DN 15 to 50
− 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
60 °C (Table 1).
Temperature range from 0 to 150 °C for un
-
balanced versions with FKM diaphragm and
FKM soft seal
Leakage class
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.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
The Type 2405 Regulator is not a safety
valve. If necessary, a suitable overpressure
protection must be installed on site in the
plant section.
Options
− With pressure balancing (see Fig. 5)
−
Pressure tapping directly at the valve in-
stead of over an external control line
with 0.8 to 2.5 bar, 2 to 5 bar and 4.5
to 10 bar
