As an important supporting mechanical products, brass valves and brass fittings are widely used in electric power, petrochemical, metallurgy, environmental protection, coal and other fields of the national economy and water conservancy, urban construction and other infrastructure construction. The advanced and reliable quality of brass valves is directly related to the normal operation of industrial installations and infrastructure. Over the years, through the introduction of technology, digestion and absorption and independent development, as well as technical transformation, the whole industry has generally improved the level of product development, design and manufacturing. In addition to some high parameters and special valves, domestic valves can basically meet the needs of various fields of the national economy and infrastructure construction. The development of new valve products, toward the thermal power, nuclear power, hydro-power, large petrochemical, oil and gas gathering and transportation pipelines, coal chemical industry and metallurgy and other major engineering construction supporting the valve direction. At the same time, the development of land oil and offshore oil mining equipment supporting brass valves and metallurgical, large ethylene, high pressure polyethylene and other major projects supporting special valves and large diameter valves; Developing valves of new materials and all kinds of environmental protection for city construction. In addition, the brass valves maintenance service and replacement will become a new growth point of enterprise product sales, at the same time, the brass valves system integration trend will become increasingly obvious. Conventional brass valves market demand sharp decline, industry reorganization and merger accelerate. According to the needs of China’s national economic development, should focus on supporting thermal power, nuclear power, hydro-power, large petrochemical, oil and gas gathering and transportation pipelines, coal chemical industry and metallurgy and other major engineering construction supporting the development of new products of brass valves.
