As the control part of the fluid conveying system, the valve has the functions of cut-off, regulation, flow diversion, countercurrent prevention, diversion and pressure relief. There are many kinds and various specifications.With the continuous development of valve technology, the application field of valves is also expanding, and the demand for high-end valves is expanding, which is not only a period of innovation and development in the valve industry, but also a period to meet the challenges.

China's valve manufacturing industry after years of development, in the valve production and technology research and development, has made great progress, some enterprises and products have made good achievements, but the development and production capacity of high-end valve products is still relatively insufficient, the international competitiveness of domestic enterprises and products is not strong enough.

With the rapid development of China's economy and the gradual improvement of the degree of industrial automation, at the same time, the equipment manufacturing industry is constantly transforming and upgrading to intelligent manufacturing, coupled with the promotion of industrialization, urbanization and globalization, the development space of China's valve industry is very broad.The future of the valve industry should be high-end, domestic, modern development.Valve manufacturing enterprises should constantly improve innovation and research and development ability, improve the technical content of products, enhance their market competitiveness, but also to go out, establish an enterprise brand.
