WebMar 28, 2024 · An orifice is a plate with a hole or cutout attached to the outlet or inserted inside a pipe such that the flow passes through the orifice. The orifice, usually circular, is of known diameter and area to keep the flow regulated. As the fluid flows through an orifice, the pressure drops across the pipe. This phenomenon is also used to measure fluid … WebNov 21, 2009 · For example, a 4 N 6 valve means a 4” inlet flange, 6” outlet flange, and a N sized orifice. I would not expect to find a 1 N 2 valve though, because an “N” orifice is relatively large and a 1″x2″ relief valve is somewhat small. API 526 also has tables you can look at showing typical valve sizes for each orifice.
