What is DN?
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.
Please use the table below for your reference and if you have any other questions, please ask the Just Valves team.
