Wafer Fittings

Where in-line wafer fittings, such as ‘Butterfly Valves’ and ‘Orifice Plates' are incorporated between pairs of flanges, a single set of extra long bolts is required. The material list number for these bolts will be added to the Flange and Gasket numbers for the second flange of the pair. The first Flange will also have the Flange and Gasket serial numbers attached, since two Gaskets are necessary in total for such an assembly.
