5 Marking of the fitting
Each fitting bears the following markings as a minimum:

Indicated by an arrow
The markings (in the case of fittings made of deep-drawn stainless steel, they are etched into the body) should
neither be covered nor painted over, so that the fitting remains identifiable.

Numerical value for DN in [mm], for G in [inches]
Zahlenwert für PN in [bar], für Class in [lbs/square
inch]
Numerical value for PN in [bar], for Class in [lbs/
square inch]. Unless otherwise indicated, all data
give the overpressure above atmospheric.
If 2 numerical values are given, these apply to the
inlet and outlet pressure.
Temperatures above 50 °C entail a reduced
pressure resistance. This must be considered for
the corresponding material in accordance with the
DIN EN 1092 standard
CrNiMo steel = high-alloy austenitic steel
