标准简介：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.
