【Ten Years of Rapid Development in Chemical Processing Equipment】The first liquid hydrogen valves to pass the type test using the internal liquid hydrogen cooling method, from 1175 to 2023

Thread Content

Looking at the development of chemical engineering technology over the past decade, we celebrate the prosperity and strength of modern China. This is just a starting point to encourage further discussion among everyone; with your participation, things will become even more interesting. [Ten Years of Progress in Chemical Engineering Equipment] – A continuously updated summary thread; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. It is important to enhance quality awareness and promote high-quality development. -----------------------------------------In September 2023, the vacuum-jacketed cryogenic valves designed by Newway for liquid hydrogen received a type test certification issued by the **Special Pump and Valve Engineering Technology Research Center. Newway became the first valve manufacturer to use internal cooling with liquid hydrogen for type testing, with all performance indicators meeting the standard requirements. These series of products are manufactured in accordance with the standard T/CGMA 0405-2022 \"General Test Methods for Cryogenic Valves Used in Hydrogen Applications\". At China’s Aerospace Product Testing Center, they undergo 100 pressure-cycle life tests under liquid hydrogen conditions, using a cooling method as stringent as those encountered in actual operations. All their performance indicators meet the requirements specified in standard T/CGMA 0407-2022 \"General Technical Specifications for Cryogenic Valves Used in Hydrogen Applications\"; this industry standard was issued by the China General Machinery Industry Association on September 10, 2022. The successful development of cryogenic valves for liquid hydrogen serves as a milestone in Newway’s innovation in ultra-cryogenic valve technology, laying a solid foundation for the global adoption and dissemination of such products.
