What is nominal pressure?
Nominal, in this context, refers to the "face value". So in this case it means what the gauge "face" is indicating. Also called gauge pressure. The difference between nominal pressure and actual pressure depends on whether gauge is a calibrated instrument and is indicating the actual pressure. Nominal pressure means rated pressure, that is a nominal pressure rating applied to vehicle parts. We can always see the PN on in the specification of valves. According to such standard, we can divide valves into flange PN 10, or any other specification.
