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 Type 44-6 B Regulator bears both the CE
and EAC marks of conformity.
Dimensions and weights
Table 3-4 provides a summary of the dimen-
sions and weights. The lengths and heights
