3.1 nominal size
An alphanumeric dimensional designation for valves, consisting of the letters DN
followed by a dimensionless integer number.
NOTE: This dimensionless number is directly related to characteristic dimensions such as the bore
diameter or outer diameter (expressed in millimeters) of the end fitting. Unless otherwise specified
in the relevant standard, the dimensionless number following DN does not represent a measured
value and shal...
