Temperature range
Depending on how the regulator is config -
ured, it can be used up to max. 200 °C. The
minimum temperature is limited by the seal
material used in the regulator (see Table
3-2).
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.
Conformity
The Types 44-0 B and 44-1 B Regulators
bear both the CE and EAC marks of confor
-
mity.
Dimensions and weights

sions and weights. The lengths and heights
