通常阀门通径采用英寸或毫米表示。
用英寸表示：
用于ASME, API和BS法兰标准。
用毫米表示：
用于DIN, AS或JIS标准阀门(DIN通径前是M，AS是A，JIS是J)。
Nominal valve sizes are expressed in
inches or millimeters.
In Inches:
For use with ASME, API and BS Flange Standards.
In Millimeters:
For use with DIN, AS or JIS rated
valves (size preceded by "M" for DIN,
"A" for AS or "J" for JIS).
