Samson 44-6 B, Монтаж и эксплуатация, Страница: 18 / 66

3-4 EB 2626-2 EN
Design and principle of operation
Bypass and shut-off valves
We recommend installing a shut-off valve (1)
both upstream of the strainer and down-
stream of the regulator and installing a by-
pass line. The bypass ensures that the plant
does not need to be shut down for service
and repair work on the regulator.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
The Type 44-6 B Regulator is not a safety
valve. If necessary, a suitable overpressure
protection must be installed on site in the
plant section.
Note
3.2 Technical data
The regulator nameplate provides informa-
tion on the regulator version (see the 'Mark-
ings on the device' section).
More information is available in Data Sheet
u
T 2626.
Process medium and scope of application
The Type 44-6 B Pressure Regulator is used
to maintain the pressure upstream of the reg-
ulator to an adjusted set point.
− For liquids, gases and vapors
− Max. temperature up to 200 °C/390 °F
− Set points from 0.2 to 20 bar/3 to
290 psi
− Valve sizes G ½ to 1/½ NPT to 1 NPT
and DN 15 to 25/NPS ½ to 1
− Pressure ratings PN 25/Class 150
and 300/JIS 20K
The regulator is closed when relieved of
pressure. The valve
opens when the up -
stream pressure rises.
Leakage class
The regulator has the leakage class I accord-
ing to IEC 60534-4.
