Metal ball valves for petroleum, petrochemical and allied industries

Scope

ISO 17292:2015 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, 600;
corresponding to nominal pipe sizes NPS:
- ¼, ⅜, ½, , 1, 1 ¼, 1 ½, 2, 2 ½, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24;
and applies for pressure designations:
- Class 150; 300; 600; 800 (Class 800 applies only for valves with threaded and socket welding end);
- PN 16, 25, 40, 63, 100.
It includes provisions for testing and inspection and for valve characteristics as follows:
- flanged and butt-welded ends, in sizes 15 ≤ DN ≤ 600 (½ ≤ NPS ≤ 24);
- socket welding and threaded ends, in sizes 8 ≤ DN ≤ 50 (¼ ≤ NPS ≤ 2);
- body seat openings designated as full bore, reduced bore, and double reduced bore;
- materials.
