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.Scroll down to related links and look at "Definition of nominal pressure".
nominal diameter
Class 150 (AKA 150#) refers to the pressure/temperature rating of the valve. That class applies to steel and alloy steel valves. Common classes are 150, 300, 600, 900, 1500, 2500, 4500. There are also interpolated ratings and special classes, which basically are intermediate ratings. For more information click the Related Link shown below.
NB stands for Nominal Bore.
Will the valve DN, PN, respectively, what does this mean? PN name (pressure nominal) on behalf of Nominal pressure Units are MPa MPa For example, is J41H-16C Nominal pressure 16Kgf/cm2 Per square centimeter pressure value MPa 16Kg count if the case is PN1.6MPa The representative of the internal pipe diameter DN Units are mm mm DN50 example is the 50 mm
DIN 16 : max working Pressure is 16 bar Class 150 : max working pressure 21 bar

The Class ranges of ANSI Standards refers to the pressure and temperature limits of usage for the Product. The class ranges from 150 and goes upto 2500. They denote the different pressure ranges. For example, A 316 Stainless Steel valve in class 150 can be used only upto 275psi Same 316 Stainless Steel valve in class 1500 can be used only upto 3600psi Does that clears your doubt?
480V.

Pressure Nominal 40; 40 bar pressure rating for European flange
PN is pressure nominal. The number following is in bar = 14.5 psi/bar.
Pressure Nominal (PN) is a term used to describe the pressure that a PE Pipe is designed to safely withstand.A pipe's PN number describes the nominal pressure in bars that a pipe can support with water at 20oC.The pressure grades available according to European standards arePN 2.5 - max pressure 2.5 barPN 4 - max pressure 4 barPN 6 - max pressure 6 barPN 10 - max pressure 10 barPN 16 - max pressure 16 barTo convert bar into MPa use the formula: (PN(bar)/10) = MPa.
Pn-40,means pressure nominal for a valve
