This standard specifies the requirements for metal ball valves suitable for petroleum, petrochemical, and industrial applications—corresponding to the nominal pipe sizes in ASME B36.10—that have:
•    flanged ends in sizes DN 15 through DN 600 (NPS 1/2 through NPS 24);
•    butt-welding ends in sizes DN 15 through DN 600 (NPS 1/2 through NPS 24);
•    socket-welding ends in sizes DN 8 through DN 50 (NPS 1/4 through NPS 2); and
•    threaded ends in sizes DN 8 through DN 50 (NPS 1/4 through NPS 2).
This standard applies to metal ball valves with pressure classes as follows:
•    flanged ends in Classes 150, 300, and 600;
•    flanged ends in Classes 900, 1500, and 2500 in sizes DN 15 through DN 50 (NPS 1/2 through NPS 2) only;
•    butt-welding ends in Classes 150, 300, and 600;
•    butt-welding ends in Classes 800, 900, 1500, and 2500 in sizes DN 15 through DN 50 (NPS 1/2 through NPS 2) only;
•    socket-welding ends and socket-welding by threaded ends in Classes 150, 300, 600, 800, 900, 1500, and  2500;
•    threaded ends in Classes 150, 300, 600, and 800.
This standard establishes requirements for bore sizes described as:
•    full bore;
•    reduced bore. See more
