What do the PN after pipes and valves mean?
The number after PN is the maximum operating pressure of the valve.
16bar, the unit of the number is bar
PN indicates the pressure level of the component, but valves with a pressure level of PN16 cannot be used under 16 kg working conditions for a long time. This is the nominal pressure, not the operating pressure.
In some places it is written PN1.6 and in other places it is written PN16?
PressureNominal Pressure
PN1.6 is the new national standard expression method, the unit is MPa. 16 is the old method, unit Bar
PN is the pressure level expression of the European series in the national standard
PN refers to the nominal pressure of the valve
