Design and principle of operation
3.1 Technical data
The valve and control thermostat nameplates
provide information on the valve and control
thermostat versions (see section 2).
Process medium and scope of application
Temperature regulators for district heating
systems, heat generators, heat exchangers
and other HVAC and industrial applications.
The Type 43-1 and Type 43-2 Temperature
Regulators are designed to maintain the tem-
perature at the control thermostat sensor to
the adjusted set point.
–
Suitable for
gases and liquids
–
Max. temperature for
liquids 150 °C
–
Max. temperature for
non-flammable
gases up to 80 °C
–
Temperature set points
from 0 to 150 °C
–
Valve sizes
G ½ to 1 · DN 15 to 50
–
Pressure rating
PN 25
The regulators
close
when the temperature
rises.
Testing according to DIN EN
The
Type 43-1
and
Type 43-2
Tem-
perature Regulators are tested by the
German Technical Inspectorate (TÜV)
according to DIN EN 14597 under
the type designation 2750-0. The
register number is available on re-
quest.
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.
Noise emission
SAMSON is unable to make general state-
ments about noise emissions. The noise emis-
sions depend on the regulator version, plant
facilities and process medium.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
Dimensions and weights
Table 4 provides a summary of the dimen-
sions and weights. The lengths and heights
in the dimension diagrams are shown on
page 22.
