【Product Introduction】:

ZFVALVES LUG type Butterfly valve realizes zero leakage relying on the composite stainless steel sealing ring installed in the disc.The mainly applicable standards of lug type butterfly valve;Design and manufacture as per API 609 standard,Face to face dimension as per API 609,End flanges dimension as per ASME B16.5,Test & inspection as per API 598 standard.


【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.
