Samson 2405 - Technical Data

14 EB 2520 EN
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cong-
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
