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:

- °, ⅜, °, , 1, 1 °, 1 °, 2, 2 °, 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 (° ≤ NPS ≤ 24);

- socket welding and threaded ends, in sizes 8 ≤ DN ≤ 50 (° ≤ NPS ≤ 2);

- body seat openings designated as full bore, reduced bore, and double reduced bore;

- materials.
