In recent years, the special knife-shaped gate valve in the flue gas desulfurization and denitration project of China's petrochemical industry has been dependent on imports. However, the imported knife-shaped gate valve is not only expensive but also has a short service life and is inconvenient to maintain. In early 2014, Sinopec preferred eight companies producing knife-shaped gate valves in China. After inspection and evaluation, they finally selected three companies, including Lixin Valve Group Co., Ltd. After the company was invited by Sinopec to participate in the research project of the localization project of the project, it immediately put into the relevant research and development process. Three sets of design and R&D programs were carried out simultaneously. After repeated tests and experiments, conditions simulation tests and trials, Lixin Valve finally delivered a satisfactory answer sheet to Sinopec. The delivery time of the imported knife-shaped gate valve needs 3~4 months. The delivery time of the domestic knife-shaped gate valve is 2~3 months. The Lixin valve can be completed in only one month.
