Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Be careful with fire risks as the heat increases in July. ---------------------------------------------- The DN4800 liquid-controlled butterfly valve passed the acceptance tests successfully. From March 20 to 22, 2023, Guangdong Yuehai Pearl River Delta Water Supply Co., Ltd. held a meeting at the CNIC Technology Testing Plant to assess the design, manufacturing quality, and conduct the acceptance testing of the first DN4800 liquid-controlled butterfly valve. In accordance with the requirements of the test plan, the participants witnessed on-site all the test items specified in the contract, including shell strength, butterfly valve strength, opening under pressure, forward and reverse sealing tests of the main seal, operation/sealing of the maintenance valve seat, and operation of the hydraulic control system. The valve is simulated to reflect the actual installation conditions on-site, and joint tests are conducted; all its performance parameters meet the requirements specified in the contract and technical agreements. The main seal achieves zero leakage in both directions, while the performance of the metal seal used for maintenance far exceeds the design specifications, reaching an internationally leading level. The successful acceptance of the first DN4800 fluid-controlled butterfly valve demonstrates China National Nuclear Corporation’s comprehensive capabilities in technology development, process optimization, and fundamental research related to large-diameter valves for special operating conditions. This achievement lays a solid foundation for the company’s growth in areas such as water resources and hydropower, as well as in the conventional islands of nuclear power plants.
