Scope

This standard specifies the requirements for a series of compact gate@ globe and check valves for petroleum and natural gas industry applications. It is applicable to valves of: ?? nominal diameter sizes DN 8@ DN 10@ DN 15@ DN 20@ DN 25@ DN 32@ DN 40@ DN 50@ DN 65@ DN 80@ and DN 100; ?? corresponding to nominal pipe sizes NPS ?@ NPS 3/8@ NPS ?@ NPS ?@ NPS 1@ NPS 1?@ NPS 1?@ NPS 2@ NPS 2?@ NPS 3@ and NPS 4. It is also applicable to pressure designations of Class 150@ Class 300@ Class 600@ Class 800@ and Class 1500. Class 800 is not a listed class designation@ but is an intermediate class number widely used for socket welding and threaded end compact valves. It includes provisions for the following valve characteristics: ?? outside screw with rising stems (OS Y)@ in sizes 8 ??DN ??100 (? ??NPS ??4) and pressure designations including Class 800; ?? inside screw with rising stems (ISRS)@ in sizes 8 ??DN ??65 (? ??NPS ??2?) and pressure designations of classes ??800; ?? socket welding or threaded ends@ in sizes 8 ??DN ??65 (? ??NPS ??2?) and pressure designations of Class 800 and Class 1500; ?? flanged or butt-welding ends@ in sizes 15 ??DN ??100 (? ??NPS ??4) and pressure designations of Class 150 through Class 1500@ excluding flanged end Class 800; ?? bonnet joint construction??bolted@ welded@ and threaded with seal weld for classes ??1500 and union nut for classes ??800; ?? extended body@ in sizes 15 ??DN ??50 (? ??NPS ??2) and pressure designations of Class 800 and Class 1500; ?? bellows stem seal@ in sizes 8 ??DN ??50 (? ??NPS ??2) and pressure designations of < Class 1500; ?? bellows stem seal testing requirements; ?? standard and full-bore body seat openings; ?? materials@ as specified; ?? testing and inspection. This standard is applicable to valve end flanges in accordance with ASME B16.5@ valve body ends having tapered pipe threads to ASME B1.20.1@ valve body ends having socket weld ends to ASME B16.11 and butt-weld connections per the requirements described within this standard. If product is supplied bearing the API Monogram and manufactured at a facility licensed by API@ the requirements of Annex A shall apply.
