What is PN 16 valve?
PN is an acronym for “Pressure Nominale”. The PN is used as a prefix to the pressure rating of the Flanges. For example, the flange PN16 is designed to operate at up to 16 levels. Normal scores: PN6, PN10, PN16, PN25, PN40, PN64, PN100.
What is PN rating of valves?
PN (Pressure Nominal) is indicated in bar; for example, PN25 is 25 bar. 1 bar equals 14.5 psi. Sometimes manufacturers will include the psi rating as well. Flanged or lug-style valves are categorized by ANSI flange classes covered under ASME B16 standards.
What pressure rating is PN16?
pressure 16 bar
Nominal pressure 16 bar; maximum internal allowable pressure (in bar) of a mechanical component, considering a temperature of 20 °C.
What is PN 10 in valve?
PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric flange dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements.
What is DN and PN in valves?
Nominal diameter (DN) and nominal pressure (PN)
What is the meaning of PN 16 for pipe?
The PN abbreviation used after the size of the polyethylene pipe represents the maximum pressure that the pipe can withstand; just like PN 16 PE100 DN63 that is a HDPE Pipe made of PE100 material and 63 mm in diameter, and should withstand a pressure of 16 bar.
What is PN 40 pressure rating?
PN 40: Pressure/Temperature-Ratings acc. DIN/EN 1092-1:2018-12
| Temperature / Material | 1.4307 | 1.4462 |

What is DN valve size?
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.
What is a PN 16 flange?
‘PN’ stands for Pressure Nominale and prefixes the pressure rating, e.g. a PN16 flange is designed to operate up to 16 bar. Typical ratings include PN6, PN10, PN16, PN25, PN40, PN64, PN100. The American ANSI standard refers instead to a pressure / temperature rating termed ‘Class’. 4.
What is PN in pressure?
PN represents the virtual pressure that the tube can withstand, that is also known as nominal pressure. PN is the numerical naming of each piping component system based on its mechanical properties, which is used as reference value.
What is DN in valve size?
DN stands for diametre nominal, which denotes the size of a pipe (specifically, its inside diameter) in millimeters (mm). NPS, or nominal pipe size, is merely the non-metric equivalent in which the diameter is measured in inches (in.).
