API standards are developed under API’s American National Standards Institute accredited process. API has developed more than 700 standards
A216/A216M specification covers carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
EN ISO 5211 specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
BS EN ISO 5210 specifies the requirements for the attachment of multi-turn actuators to valves.
BS EN 558 Standard specifies the “face-to-face” (FTF) and “centre-to-face” (CTF) dimensions for PN and Class designated metal valves used in flanged pipe systems.
BS 6364 Standard specifies the requirements for the design, manufacture and testing of valves for cryogenic service. It is a requirement of this standard that the valves comply with the appropriate valve product British Standards,
BS 5352 Standard specifies requirements for forged, cast or bar stock steel wedge gate, globe stop and check valves with flanged, screwed, socket-weld or butt-weld ends, in nominal sizes 50 mm (2 in) and smaller in classes 150, 300, 600, 800 and 1500 of the following types.
BS 5351 Standard specifies the valve seat and body pressure/temperature ratings, and the design, including materials, dimensions, operation, performance, testing and marking, of straightway steel ball valves having specified wall thickness, an antistatic feature and fire tested design.
BS 2995 Standard specifies requirements for cast and forged carbon and alloy steel screwed and socket- welding valves for the petroleum industry in sizes 2 in andsmaller.
BS 1873 Standard specifies requirements for cast or forged carbon and alloy steel outside screw and yoke globe valve and globe stop and check valves, straight pattern, angle pattern and (oblique) Y pattern, with flanged or butt-welding ends in nominal sizes within the range of15 mm to 400 mm( in to 16 in) and Classes 150 to 2500.
BS 1868 Standard specifies requirements for cast steel check valves or forged steel check valves with flanged or butt-welding ends of the following types.
