What is DN valve size?

DN stands for ‘Diameter Nominal’. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm. We refer to a 12″ flange as DN300, when in fact it is 304mm.

What does dn50 mean?

For reference, a DN 50 pipe indicates a pipe with an external diameter of 60.3 mm and a wall thickness of 3.65 mm according to EN 10255 (resulting indoor diameter of 53 mm).

What is DN and OD?

NPS is referred to as nominal pipe size which is the US customary system while DN is referred to as nominal diameter which is the used in international standards. O.D is the outside diameter of the piping component which can be actually measured.

Is DN and NB the same?

In the inch system, nominal bore is abbreviated as NB; in metric systems, it is “diameter nominal” (DN), or Nominal Pipe Size (NPS) in North America. Above that size, the NB is the SAME as the outside diameter!

What is DN and PN?

Indeed, only elements having the same DN and the same nominal pressure (PN) can be coupled. A pipe’s nominal pressure describes the maximum internal pressure that the pipe and its joints are capable of withstanding and it is expressed in bars.
