The U.S. Series 9000 GCF control valve is available with ANSI raisedface flanges. The flanges are socket welded to the body and flange. The flange and nipple material is the same material as the body material. Flange faces have concentric serrations to provide superior gasket sealing. The unit is rated for either ANSI Class 150 or 300, depending on the flange. When the valve is supplied with CL150 flanges, the pressure vs. temperature rating of the valve assumes the rating of the flange or the packing, whichever is lower. Consult the factory for limits of standard and optional inner valve materials.
