API Std 608

This standard specifies the requirements for metal ball valves suitable for petroleum, petrochemical, and industrial applications 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);threaded ends in sizes DN 8 through DN 50 (NPS 1/4 through NPS 2).Corresponding to the nominal pipe sizes in ASME B36.10M.

This standard applies to metal ball valves with pressure classes as follows:flanged ends in Classes 150, 300, and 600;butt-welding ends in Classes 150, 300, and 600;socket-welding ends in Classes 150, 300, 600, and 800;threaded ends in Classes 150, 300, 600, and 800.This standard establishes requirements for bore sizes described as:full bore;single reduced bore;double reduced bore.This standard applies to floating (seat-supported) ball (Figure B.1) and trunnion ball valve designs (Figure B.2). These figures are to be used only for the purpose of establishing standard nomenclature for valve components - other floating and trunnion designs also exist.This standard establishes additional requirements for ball valves that are otherwise in full conformance to the requirements of ASME B16.34, Standard Class.
