Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This Standard is not equivalent to its counterpart ISO 10434: 2004/API 600-2001 "Bolted Bonnet Steel Gate Valves for the Petroleum, Petrochemical and Allied Industries", and by comparison, their technical contents and text structures differ significantly. ——The dimension requirement of butt-welding ends in 5.3.2 of ISO 10434: 2004 were cancelled; ——The dimension requirement of auxiliary connections in 5.12 of ISO 10434: 2004 were cancelled; ——The welding for fabrication and repair of 6.3 was not adopted; ——The specific contents of Chapter 7 Testing, inspection and examination was not adopted; ——The minimum body and seat diameters were added. This Standard is a revision of GB/T 12234-1989 "General Purpose Industrial Valves-Flanged and Butt-weld Steel Gate Valves". The main changes between this Standard and GB/T 12234-1989 are as follows: ——The standard name was revised to "Bolted Bonnet Steel Gate Valves for the Petroleum and Natural Gas Industries"; ——The minimum body wall thickness requirement was revised; ——The minimum body and seat diameter requirements were added; ——The bolt tensile stress requirement was modified; ——The weld-deposited thickness requirement of sealing surface was modified; ——The minimum stem diameter requirement was modified; ——The packing and packing box requirements were modified; ——The body-to-bonnet bolting requirement was modified; ——The potential pressure life test times requirement and technical contents of non-destructive inspection were added; ——The materials requirements were modified and the stem material hardness requirement was added; ——The test methods and inspection requirements were modified and type test items and requirements were added; ——The marking details and supply requirement were modified; ——The details of Appendix A "selection of gate and seat sealing surfaces and trim materials" in GB/T 12234-1989 GB/T 12234-1989 was transferred to the text; ——Appendix A "Order Contract Data Sheet" was added. This Standard replaces GB/T 12234-1989 from the implementation date hereof. Appendix A of this standard is informative. This Standard was proposed by China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee on Valves of Standardization Administration of China (SAC/TC 188).
