API 600 Bolted Bonnet Steel Gate Valves
The basic requirements and practices for flanged and butt-welding end steel gate valves of bolted bonnet construction which parallel those given in API 600, Tenth Edition. In order to maintain compatibility with the flanges defined in ISO 7005-1 and the flanges in ASME B16.5, valves have been designated to be PN-marked for the former and Class-marked for the latter. It is not the purpose of this International Standard to replace ISO 6002 or any other International Standard
