Design and principle of operation
3.1 Technical data
The regulator's nameplate contains informa-
tion on the regulator version (see sec-
tion2.1).
Process medium and scope of application
The Type2488N/5857 Pressure-indepen-
dent Control Valve (PICV) is suitable for the
control of water and non-ammable gases.
− Non-ammable gases up to 80°C
− Liquids up to 110°C
The regulator is open when relieved of pres-
sure. It closes when the downstream pressure
rises above the adjusted set point.
Compliance
The Type2488N/5857 Regulator bears
both the CE and EAC marks of conformity.
Temperature range
The Type2488N/5857 Regulator is de-
signed for a temperature range from –10 to
+110°C (14 to 300°F).
Leakage class
All regulators have the leakage class I ac-
cording to IEC60534-4.
Noise emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the valve version, plant facilities and process
medium. On request, SAMSON can perform
calculations according to IEC60534,
Part8-3 and Part8-4 or VDMA24422 (edi-
tion89).
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the valve.
Dimensions and weights
Fig.3 as well as Table1 and Table2 provide
a summary of the dimensions and weights of
the Type2488N/5857 Regulator. The
lengths and heights in the dimensional draw-
ings are shown on p.13 onwards.
