What does \"Yamaki control valve size 1B B\" mean?
Reply #22016-06-29
I searched through a lot of information but couldn’t find any answers; later, I happened to come across information stating that BIN refers to imperial units based on inches, while BFT refers to imperial units based on feet. Here, B probably refers to inches. My personal understanding.

The parameters of this valve follow Japanese standards (JIS). The nominal diameter is available in metric and imperial units, denoted by A and B respectively; the size units are mm and inches (”). Here, 1B refers to the imperial system, indicating a nominal diameter of DN1″, where 1″ (inch) = 25.4 mm
