Competition in the petrochemical sector remains fierce, imposing the most stringent requirements on valve equipment. The valve industry is gradually realizing automation, which promotes the overall performance improvement of valve equipment and drives the development of multi‑functional, high‑efficiency and low‑consumption petrochemical valves. The annual output value of domestic petrochemical enterprises reaches hundreds of billions RMB, indicating a huge domestic valve market. After more than 60 years of development, the refining industry has achieved rapid expansion in production scale. Driven by a series of policy measures, the output value and output of China’s refining and petrochemical industries keep growing, structural adjustment is steadily advanced, and the sector maintains sound development momentum.
