The competition in the petrochemical industry has always been fierce. The requirements for valve equipment have also been the most stringent. The valve industry has gradually achieved automation, promoted the improvement of the overall level of valve equipment, and developed multi-functional, high-efficiency, and low-consumption petrochemical valve equipment. Annual output value of China’s petrochemical enterprises is in the hundreds of billions, which shows that China has a large valve market. After more than 60 years of development, the oil refining industry has rapidly expanded its production scale. Driven by a series of policies and measures, the output value and output of China’s refining and petrochemical industries have continued to grow, structural adjustments have gradually advanced, and good momentum has continued to maintain.
