Is PN40 the same as PN16?
Standards of flanges vary worldwide, meaning that in most cases they are not interchangeable. The size, drilling and pressure range will be different (ie a PN16 flange is not rated to the same pressure class as a PN40 flange… nor would a PN16 flange fit an ANSI 150 flange).
What is dn65 flange size?
2 1/2″
2 1/2″ NB (DN65) Flange Table – Flange Dimensions
| 2 1/2″ | Flange Diameter | Diameter of Raised Face |

What is PN40 pressure rating?
PN stands for Nominal Pressure and roughly equates to the number of bar i.e. the cold working pressure of PN10 is 10 bar. Ratings range from PN2. 5 to PN420….Overview.
| 2 1/2″ | DN65 |
|---|---|
| 8″ | DN200 |
| 10″ | DN250 |
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 the size of dn65 valve?
2-1/2 inch
This valve is rated for 16 bar and is operated by hand, but can be used with an actuator (ISO 5211 F05). The nominal diameter is 65 mm (2-1/2 inch) and has a wafer type flange. The Cast iron (GGG40) housing, stainless steel disc and NBR seal make it durable and allows for a media temperature between 5°C and 85°C.
What is DN 25 valve?
DN stands for ‘Diameter Nominal’. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm.
What does DN stand for in valve size?
diametre nominal
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.).
How long of a bolt should I use?
A good rule to follow is to always use the shortest standard length fastener that gives a minimum one thread protrusion. Small and/or short bolts come in 1/8- or 1/4-inch increments. As the fastener gets larger and longer the increments change to 1/2 inch.
What length bolt do I need?
A typical rule of thumb . . . Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt.
