What do these letters and numbers on the hand valve body mean?
Thread Content
As the title suggests, it’s a gate valve, and the valve body is marked with BFMC 3 300 WCB A 1599. Could you please tell me what each of these terms means? Thank you!
WCB refers to the valve body material being cast steel; 300 might be the design pressure (in pounds of pressure), i.e., 300 lbs? I’m not sure about the other values either. Is there anyone who knows this well and can explain it?
BFMC is a trademark or manufacturer’s name; 3 refers to the nominal diameter of 3\", and A 1599 is the pipe fitting number or valve code used by the owner or design company for identification.
According to the arrangement described by the poster, the usual meanings are as follows: BFMC ----------------- logo 3 ------------------- nominal bore NPS3″ 300 ------------------- pressure rating 300Lb WCB ------------------ valve body material is WCB A 1599 --------------- heat No. furnace number
