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.
Temperature range
Depending on how the Type 43-3 Regulator
is configured, it can be used up to max.
150 °C. The minimum temperature is limited
by the seal material used in the regulator
(see Table 3-1).
Dimensions and weights
Table 3-3 provides a summary of the dimen-
sions and weights. The lengths and heights
