Valves used for fluid control range from simple shut-off devices to extremely complex self-control systems, with a wide variety and specifications. The diameter of valves ranges from very small instrument valves used in aerospace to industrial pipeline valves with diameters of several meters and weights of over ten tons; The working pressure can range from vacuum to ultra-high pressure of 1000Mpa; The working temperature can range from ultra-low temperature of -269 ℃ to high temperature of 1430 ℃; The transmission mode can be manual, pneumatic, hydraulic, electric, electro pneumatic linkage, electro hydraulic linkage, or even electromagnetic drive, etc; It can act according to predetermined requirements under the action of pressure, temperature, and other forms of sensing signals, or perform simple opening or closing without relying on sensing signals; It can be used to control the flow of various types of fluids such as air, water, steam, corrosive chemical media, mud, liquid metals, and radioactive substances.
After more than 50 years of development, China's valve industry could only produce over 600 varieties and 2700 specifications of valve products before the 1980s, lacking the ability to design and produce high parameter, high-tech valves. In order to meet the rapid development of industrial and agricultural production in China's demand for high parameter and high-tech valves, since the early 1980s, China has adopted a combination of independent development and technology introduction to develop valve technology. Some key valve enterprises have increased their research and development efforts, leading to a peak in the introduction of valve technology. Since the 1980s, through the introduction of technology, digestion and absorption combined with independent research and development, China's valve manufacturing level and product quality have greatly improved compared to before. Since the end of the last century, the valve industry has experienced faster development. Valve manufacturers have grown from small to large and have made continuous progress in research, development, and production. They have produced 12 categories of valve products, including gate valves, globe valves, throttle valves, ball valves, butterfly valves, diaphragm valves, plug valves, check valves, safety valves, pressure reducing valves, drain valves, and other valves, with over 3000 models and 40000 specifications.
