	API 598	This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonresilient- and nonmetallic-seated, and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant. Covers both required and optional pressure tests by the valve manufacturer at his plant.

	API 600	API 600 is the primary steel gate valve purchase specification. Valve design and construction criteria are detailed, as well as materials and trim designations. An appendix contains information pertaining to pressure seal valves. ISO Standard 10434 is essentially the same as API 600, only published in the ISO format. This standard is for the convenience of purchasers and manufacturers who order, fabricate, or install steel gate valves. Covers steel gate valves with flanged or butt-welding ends in sizes NPS 1 through NPS 24. These sizes correspond to nominal pipe sizes in ASME B36.10M.

	API 602	This standard is a purchase specification for threaded-end, socket-welding-end, buttwelding-end, and flanged-end compact steel gate valves in sizes NPS 4 and smaller. The term compact is used to distinguish the reduced-port valves covered by this standard from the full-port valves described in the API standard 600, Steel Gates, Flanged and Buttwelding Ends. Inspection and testing requirements for these valves are covered fully in API Standard 598
