DN is an acronym for Diameter Normal that refer to metric designations of pipes that conform to the International Standards Organisation (ISO). DN100 refers to a pipe with a Diameter Normal of 100 mm and a Nominal Pipe Size (NPS) of 4 inches.Answer:Actually the N means nominal. Because the actual size of the pipe is nowhere what the nominal size is.
DN 50 means: "DN": Diametre nominel - Nominal diameter of the valve, and "50" is the size of the valve in [mm]. Alternative is NPS (Nominal pipe size in inches).
DN": Diametre nominel - Nominal diameter of the valve, and "50" is the size of the valve in [mm]. Alternative is NPS (Nominal pipe size in inches).
