What does "DN15" mean? What does "PN 16" mean?
DN15 refers to the diameter of the valve, that is to connect the caliber of the pipe.PN16 means pressure, that is, 16 kilograms (1.6MPa).
Valve nominal diameter 15mm, valve nominal pressure 1.6MPa
Valve DN15 refers to the nominal diameter of the valve 15mm, PN, 16 refers to the pressure of the valve is 1.6MPa.Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter). DN is the nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of the general caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.
