Due to the wide use of valves, they play an increasingly important role in industrial production. In petroleum and chemical production, valves control the normal operation of all production equipment and processes. However, compared to other products, valves are often overlooked. When installing machinery and equipment, people often focus on the main machinery and equipment, such as compressors, high-pressure vessels, boilers, etc., ignoring the selection and installation of valves. Improper selection and installation of valves can reduce the overall production efficiency or stop production, or cause various other accidents. Therefore, careful and responsible work must be carried out in the selection, installation, and use of valves, especially in modern industrial production and construction.
