Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. The global valve manufacturing industry is mainly concentrated in North America, Europe, Japan, and China. Economically developed regions such as Europe and Japan mainly produce metallurgy, petrochemical, and nuclear power valves. In East Asia and Southeast Asia, such as China and India, the market for drainage valves has been growing faster due to the influence of demand. The number of China's valve companies ranks among the top in the world, but the overall size of domestic water valve companies is relatively small and the industry concentration is low. In 2011, the national valve production reached 5,589,700 tons, a year-on-year increase of 14.5%.

Shang Pu consulting machinery industry analysts believe that in recent years, the rapid development of the valve industry, the industry prospects are good, there are several major positive factors: 1. The investment in environmental protection continues to increase. With the increase of national attention to environmental protection and water resources, it is required to increase the recycling rate of Zhongshui, increase the treatment of industrial water pollution, and improve the discharge standard of domestic sewage, which will increase the demand for valves and environmental protection equipment; 2 . Urbanization continues to accelerate. With the continuous development of economy, the construction of domestic drainage projects has gradually expanded to second-tier and third-tier cities and extended to some townships. The demand for domestic sewage treatment continues to expand, and the demand for drainage valves is increasing. 3. National policy support. With the gradual advancement of the country's policy of accelerating the revitalization of equipment manufacturing, general basic manufacturing will be further developed. 4. Strong market demand. With the steady and steady development of the state-owned economy, fixed investment will gradually expand; 5. Global drainage valve companies continue to flood our country. With the influence of resources and labor costs in developed countries, the drainage valve manufacturing industry has continued to shift to China, driving the prosperity and development of China's valve industry.

According to the "2011-2016 China Valve Industry Research and Investment Forecast Report", in recent years, China, India and other developing countries have made rapid development of the drainage valve industry, and their export and market share have continuously expanded, and they have become an important industry production. Base and main product sales market.
