適用范圍：This International Standard specifies the requirements for a series of steel ball valves suitable for general-purpose industrial applications.It covers valves of the nominal sizes (see ISO 6708 and ASME B16.34)— DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80, 100, 150, 200, 250, 300, 350, 400, 450, 500 (NPS 1/4, 3/8, 1/2, 3/4, 1,11/4, 11/2,2,21/2,3,4,6,8, 10, 12, 14, 16, 18 and 20),and is applicable to the following pressure designations (see ISO 7268 or EN 1333, and ASME B16.34):— Class 150; 300; 600; 900 and PN 10; 16; 25; 40; 63; 100. It includes provisions for valve characteristics as follows 1):— flanged and butt-welded ends in sizes 15 ≤ DN ≤500 (1/2≤ NPS s≤ 20);— socket welding ends in sizes 8 ≤ DN ≤ 100 (1/4 ≤ NPS≤ 4);— threaded ends in sizes 8 ≤ DN ≤ 50 (1/4 ≤ NPS ≤ 2);— body seat openings designated as full bore, reduced bore, and double reduced bore;— materials;— testing and inspection.
