適用范圍：This International Standard specifies the requirements for a series of metal ball valves suitable for petroleum, petrochemical, natural gas plants, and related industrial applications. It covers valves of the nominal sizes DN — 8; 10; 15; 20; 25; 32; 40; 50; 65; 80; 100; 150; 200; 250; 300; 350; 400; 450; 500 corresponding to nominal pipe sizes NPS — 1/4; 3/8; 1/2; 3/4; 1; 5/4; 3/2; 2; 5/2; 3; 4; 6; 8; 10; 12; 14; 16; 18; 20; and applies for pressure designations — Class 150; 300; 600; 800 (Class 800 applies only for valves with reduced bore and with threaded and socket welding end); — PN 16; 25; 40. It includes provisions for testing and inspection and for valve characteristics as follows: — flanged and butt-welded ends, in sizes 15 ≤ DN ≤ 500 (1/2 ≤ NPS ≤ 20); — socket welding and 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.
