In the petrochemical production plant, valves play a vital role. Petrochemical production of various types of gases and liquids through various valves, according to the production process needs to be blocked or transported to a variety of containers and process equipment. Petrochemical production of commonly used valves are divided into two categories of general-purpose valves and special valves. Petroleum applications in the valve covers all aspects of the production from raw material handling to the product, there are many types of valves, each type of valve has its specific functions and application scenarios, the design and manufacture of valves are also progressing to meet the petrochemical production of higher requirements for the performance of the valve.

Natural gas valves play a vital role in the transportation and use of natural gas. They are mainly used to control the flow of natural gas, prevent backflow, isolate faulty sections, regulate flow, etc. Natural gas pipelines may also use other types of valves, which play their respective roles in specific application scenarios and work together to ensure the safe and efficient operation of natural gas pipeline systems. When selecting valves, comprehensive consideration needs to be made according to the specific needs of the pipeline system, the working environment and the use of the scene, in order to ensure the performance, reliability and safety of the valves. At the same time, regular inspection, maintenance and replacement of valves are also key measures to ensure the long-term stable operation of natural gas pipeline systems.

Valves play a vital role in the heating industry, they are used to control the flow of hot water or steam to ensure the efficient operation of the heating system and people's comfortable life. They are mainly used to control the temperature of the heating system, emergency cut-off function, heating system settings, valve selection, application of automatic balancing valves, and maintenance of heating valves. The application of valves in the heating industry covers a wide range of aspects, such as temperature control, zone control, emergency cut-off, system settings, valve selection, application of automatic balancing valves, and maintenance of heating valves, etc., which work together to ensure the stable and efficient operation of the heating system.

Valves are widely used in the chemical industry and they play a vital role in the chemical production process. Valves are mainly used to control the flow, pressure, temperature and direction of fluids to ensure the smooth running of the chemical process. The following are some specific application scenarios: The chemical industry has very high performance requirements for valves, including sealing performance, corrosion resistance, high temperature resistance, fluid resistance and so on. With the development of technology, chemical valves are moving towards intelligence, high efficiency and environmental protection to meet the constant changes and challenges of the chemical industry.

In the metallurgical industry, valves are widely used and they play an important role in different production processes. Valves designed specifically for the metallurgical industry are used in metallurgical systems mainly in water-through cooling devices, where the injection of cooling water is controlled by controlling the opening and closing speeds of the valves, so as to achieve precise temperature control. The selection and application of valves for the metallurgical industry need to consider the nature of the medium, the working conditions (such as temperature and pressure), as well as the control accuracy and reliability of the valve. With the development of technology, the design and manufacture of valves for the metallurgical industry are also advancing to meet higher production requirements and environmental standards.

Valves play a vital role in water conservancy, not only to ensure the smoothness of the water treatment process, but also to ensure the safety of water quality and stability of water supply. With the progress of science and technology, smart valves are gradually applied in water conservancy. Smart valves integrated automation control technology, can realize remote control, automatic adjustment and other functions. Valves in the water conservancy application covers the entire process from raw water treatment to wastewater treatment, their correct selection and maintenance is essential to ensure the normal operation of the water conservancy. At the same time, the development of intelligent valves provides new possibilities for the modern management of water conservancy.
