本文件规定了法兰或对焊管道系统用金属阀体蝶阀的设计、材料（如钢、铸铁、球墨铸铁、铜合金）、压力/温度额定值和试验的一般要求。本文件适用于所有工业应用中使用的金属蝶阀。相关应用标准中给出的附加要求可适用于用于更具体应用的蝶阀（例如，水工业、化工和石化过程工业、石油和天然气工业）。本文件涵盖以下公称尺寸、DN和NPS的蝶阀:-？DN 40；50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; 450; 500; (550); 600; (650); 700; 750; 800; 900; 1？000;1？050; 1？200; 1？400; 1？500; 1？600; 1？800; 2？000; 2？200; 2？400.-核动力源1；2.2.3.4.5.6.8.10; 12; 14; 16; 18; 20; (22); 24; (26); 28; 30; 32; 36; 40; 42; 48; 54; 56; 60; 64; 66; 72; 78; 80; 84; 88; 90; 96本文件适用于以下压力名称、PN和等级的蝶阀:-？PN？2,5；PN？6；PN？10；PN？16；PN？25；PN？40；PN？63；PN？100；-？25级，125级；150; 250; 300; 600注？1？所列标称尺寸可能不适用于所有压力名称。注？2？括号中列出的标称尺寸不是常见的行业尺寸，但在一些应用标准中使用。
This document specifies the general requirements for design, materials (e.g. steel, cast iron, ductile iron, copper alloy), pressure/temperature ratings and testing for butterfly valves having metallic bodies for use in flanged or butt-welding piping systems.This document applies to metallic butterfly valves used for all industrial applications.Additional requirements given in the relevant application standards can apply to butterfly valves used for more specific applications (e.g. for the water industry, the chemical and petrochemical process industry, the oil and gas industry).This document covers butterfly valves of the following nominal sizes, DN and NPS:— DN 40; 50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; 450; 500; (550); 600; (650); 700; 750; 800; 900; 1 000; 1 050; 1 200; 1 400; 1 500; 1 600; 1 800; 2 000; 2 200; 2 400.— NPS 1？; 2; 2？; 3; 4; 5; 6; 8; 10; 12; 14; 16; 18; 20; (22); 24; (26); 28; 30; 32; 36; 40; 42; 48; 54; 56; 60; 64; 66; 72; 78; 80; 84; 88; 90; 96.This document is applicable to butterfly valves of the following pressure designations, PN and Class:— PN 2,5; PN 6; PN 10; PN 16; PN 25; PN 40; PN 63; PN 100;— Class 25, 125; 150; 250; 300; 600.NOTE 1 It is possible that the nominal sizes listed are not available for all pressure designations.NOTE 2 Nominal sizes listed in parenthesis are not common industry sizes, but are used in some application standards.
