Technical Data - Samson 42-10 Mounting And Operating Instructions

3.2 Technical data

The valve and actuator nameplates provide
information on the valve and actuator ver-
sions (see the 'Markings on the device' sec-
tion).
Note
More information is available in Data Sheet
u T 3009.
Conformity
The Type 42-10 RS Regulator bears both the
CE and EAC marks of conformity.
Process medium and scope of application
The Type 42-10 RS Check Valve is used to
prevent the backflow protection of a medi-
um.

Design and principle of operation
The regulator is closed when relieved of
pressure. The regulator is open when the up-
stream pressure is greater than the down-
stream pressure. The regulator closes when
the downstream pressure rises.
Leakage class
The soft-seated regulator has the leakage
class VI according to IEC 60534-4.
Temperature range
Depending on how the regulator is config-
ured, it can be used up to temperatures of
220 °C/430 °F (see Table 3-1). The mini-
mum temperature is limited by the accesso-
ries used and the actuator's diaphragm ma-
terial (u T 3009).
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
Fig. 3-4 provides a summary of the dimen-
sions and weights. The lengths and heights
