permitted medium temperature for body
Body material
Cast body (VG) 1.4435 (AISI 316L)
1.4435 BN2 (AISI 316L)
Forged body (VS) according to ASME BPE

Tab. 2: Permitted medium temperature for body
permitted medium temperature for diaphragms
The indicated medium temperatures apply only to media
which do not corrode or swell the diaphragm materials.
The behaviour of the medium with respect to the dia-
phragm may be changed by the medium temperature.
The function properties, in particular the service life of the
diaphragm, may deteriorate if the medium temperature
increases.
