Recently, the Chinese China 22mcc group Minmetals precision forging company to organize JB/T 13274-2017 "valve multi precision forging process and the" JB/T 13275-2017 "principle for the preparation of multi precision forging parts valve general technical conditions" officially allowed to publish, the implementation date of April 1, 2018.

The standard is part of China's independent research and development standards, and has no corresponding international or foreign standards. It solves the problem of lack of multi-directional forging technology standard of valve industry in China, and its technology level is advanced in China. In 2012 a major national high-end CNC machine tools and basic manufacturing equipment science and technology projects, "large forging manufacturing" Research on generic technology as research subject, the two criteria is formed based on the theory research, the research result is important. The study and formulation and release will improve the domestic high-end valve forging supporting design and production capacity of the two standards, and further promote the stability of the valve body of multi die forging high-end products production and development standard, based on the development of solid domestic valve multi die forging industry, will also be on the forging industry in China implementation of energy and material, and play a positive role in promoting.
