In the petrochemical refining process conditions are flammable, explosive, high temperature, high pressure, high leakage grade, High-Pressure Hydrogen-Adjacent, these conditions are extremely critical for valves; By the end of 2021, the number of 10 million tons large refineries has reached 32, these large refining enterprises, play the advantage of scale utilization of resources, have realized the integration of oil refining + olefin + aromatics. PCV products are widely used in Crude Distillation Unit, catalytic cracking unit, hydrogenation unit, hydrocracking unit, catalytic reforming unit, alkylation unit, aromatics separation unit and other units, and the application reference is all over the country.

Fine chemical is one of the dynamic emerging fields in the chemical industry. It is an important part of the new material. It includes medicine, pesticides, dyes, coatings, pigments, reagents, adhesives, water treatment agents, catalysts, additives and other more than 40 industries and categories, which can be said to be closely related to human life. Vigorously developing fine chemical industry has become the strategic focus of all countries to adjust the structure of chemical industry, enhance the level of chemical industry and expand economic benefits. The development of fine chemical industry provides a guarantee for the development of high and new technology, such as biotechnology, information technology, new materials, new energy technology and environmental protection. At present, in the vigorous development period of the fine chemical industry, greater demand has been placed on control valves, the application conditions are more and more complex, the control valve manufacturers paid more attention to the field.

The sustained and rapid development of China's national economy has released greater demand on China's energy industry. At present, China has formulated policies based on thermal power, vigorously develop hydropower, and moderately develop new energy sources, such as nuclear power and wind power generation. The construction strategy of nuclear power in China is changing from experimental and compensatory to strategic and aggressive development. This is an excellent development opportunity for China's nuclear power industry, and the huge demand for nuclear power plant valves has brought a broad market prospects to the domestic and foreign market valve manufacturers.

The rapid development of large-scale coal chemical industry needs the corresponding technical and equipment support, especially the coal to oil, methanol, synthetic ammonia, and coal to olefin and other coal chemical industry needs a large number of large coal chemical valve equipment. Among them, coal to oil (with coal liquefaction legal oil), is a key development of a new technology, coal direct liquefaction units’ process conditions are extremely critical, the requirements for the valve is very high. Coal to oil is characterized by flammable, high temperature and corrosion and wear, the corresponding requirements of the valve will be very high.

With China's long-term rapid economic growth of the demand for steel, the steel metallurgy industry has been an important basic industry of the national economy, is the supporting industry to achieve industrialization, is a technology, capital, resource, energy-intensive industry. Energy saving and consumption reduction and resource saving are the urgent major issues to be solved in the metallurgical industry. Metallurgical industry is also facing the transformation and renewal of the existing equipment, the elimination of high energy consumption, heavy environmental pollution of backward equipment, how to develop the iron and steel industry to a higher level, energy conservation, environmental protection and variety structure optimization is increasingly increasing, which requires a large number of advanced equipment to support, iron and steel metallurgy valve has a huge market. Energy saving and emission reduction valve equipment has gained more potential market.

The super large air separation equipment is composed of air compression system, large air precooling system, super large molecular sieve purification system, air pressurization system, pressurized turbine expander system and super large distillation system and heat exchange system. Due to the large size of the supporting unit equipment and the high manufacturing process requirements, the supporting valve selection is particularly important, which is directly related to the production safety, system controlling performance, production quality and investment costs.

Currently LNG valve technology is in a period of rapid growth. In the rapid development process of LNG industry, the demand for supporting cryogenic valves is increasing. Because LNG has the remarkable characteristics of flammable and explosive ultra-low temperature, and LNG factory is usually located in the coastal salt fog environment, its quality directly affects the safety operation of the equipment, so the selection design of low temperature valve puts forward higher requirements.

With the development, the progress of science and technology, and the continuous improvement of people's living standards, the application field of bio-chemical industry has been continuously expanded and extended, followed by the large batch, modern, automated industrial production of pharmaceutical supplies.Modern pharmaceutical factory fermentation workshop use valves to cut off or communicate steam, water, media, air and other fluids, adjust the flow of fluid, control the pressure in the pipeline or container.

With the development of the pesticide and pharmaceutical industry, the requirements of cleaning, sterilization and sealing of the reaction equipment are becoming more and more stringent. Therefore, the valves used in working conditions are often required to achieve zero leakage, to avoid drug contamination in the production process. The whole operation space has no irritating odor, no smoke, to the valve manufacturing industry has put forward strict requirements. At the same time, under the development trend of pesticide industry, all kinds of valves will be more widely used in pesticide pharmaceutical industry.

Since the 20th century, chemical fibers have been produced with the development of polymer materials. The advent of chemical fiber has changed the history of only using natural fiber as a raw material for thousands of years, and opened up a broad prospect for obtaining new and more superior textile fiber. The raw materials of chemical fiber come from oil, natural gas, coal and agricultural and forestry by-products. With the rapid growth of the petroleum industry, the development of the variety, quantity and technical level of synthetic fiber far exceeds the production of man-made fiber. In the production process of the chemical fiber industry, the safety and stability of the pipeline system is the key to the production, and the valve products need to be able to deal with the complex situation in the chemical fiber pipeline system, so that the pipeline system in the production process runs more freely.
