Samson EB 2111 - Technical Data

3-6 EB2111/2121/2123 EN
Design and principle of operation
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.
Temperature range
Dependingonhowtheregulatoriscong-
ured, it can be used up to temperatures of
350°C/660°F(seeTable 3-2). The mini-
mum temperature is limited by the accesso-
ries used and the actuator's diaphragm ma-
terial (uT2121 and uT2123).
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 3-7 to Table 3-9 provide an overview
of the dimensions and weights. The lengths
and heights in the dimensional drawings are
shownonpages3-12 and 3-13.
3.3 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 Sheets
uT2111, uT2121 and uT2123.
Process medium and scope of application
The temperature regulators are designed to
maintain the temperature to the adjusted set
point.
− For liquids, gases and vapors
− Max. temperature 350°C/175°F
− Set points from –10 to +250°C/15 to
480°F
− ValvesizesDN15 to 150/NPS½ to 6
− Pressure ratings PN40 to 40/Class150
to 300
TheType1andType4Regulatorsareopen
when relieved of pressure. The valve closes
when the temperature rises.
TheType4uRegulatorisclosedwhenre-
lieved of pressure. The valve opens when the
temperature rises.
Conformity
TheType1,Type4andType4uRegulators
bearboththeCEandEACmarksofconfor-
mity.
