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.
Temperature range
Depending on how the regulator is config-
ured, it can be used up to temperatures of
150 °C (see Table 3-1). The minimum tem-
perature is limited by the accessories used
and the actuator's diaphragm material
(u T 3018).

Design and principle of operation
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.
Dimensions and weights
Fig. 3-5 to Fig. 3-7 provide an overview of
the dimensions and weights. The lengths and
heights in the dimensional drawings are
shown on pages 3-12 to 3-15.
