The competition in the petrochemical industry has always been fierce, and the requirements for valve equipment are also very strict. The valve industry is gradually realizing automation, promoting the overall level of valve equipment, and developing multi-functional and low-consumption petrochemical valve equipment. The annual output value of China's petrochemical enterprises is in the hundreds of billions of years, which shows that our country has a large valve market. After more than 60 years of development, oil refining industry has rapidly expanded its production scale. Under the promotion of a series of policy measures, the output value and output of China's refining and petrochemical industries have continued to grow, and structural adjustment has been gradually advanced, continuing to maintain a good momentum of development.
