This paper introduces the new technology of large-scale hydrogenation plant and the technical requirements of intelligent refinery construction for the control,o peration and long period safe operation of high-pressure valve. The structural design,material selection,manufacture, inspection and test procedures of high-pressure valves used in hydrogenation plant under different working conditions are analyzed. The problems to be solved and the developing trend of domestic production of high-pressure valves for hydrogenation units are pointed out. The improvement measures are put forward to improve the quality of valve mass production,perfect the quality control of outsourcing parts,o ptimize the product detail design and assembly process,and strengthen the r&d of new valve hydrogenation process products.
