【Application of Flange Dimension】:

ZFVALVES is a professional American standard butterfly valve manufacturer. Series B is mentioned in standard ASME B16.47, which is a flange dimension standard. The flange size of the American standard butterfly valve is usually ASME B 16.5 below 24 inches. There is only one system in this standard. Starting from 26 inches, the flange standard ASME B16.47 is used. There are two type dimensions in ASME B16.47 : Series A and Series B . 

The flange sizes of the two series are different, including the outer diameter of the flange, the diameter of cernter of bolt hole, the number of holes, the diameter of the hole, and the thickness of the flange. So the price of the two is different. Usually, Series B flange weight will be lighter than Series A, so the cost of the valve with flange series B will be lower.
