The valve industry must implement advanced standards to improve product quality

China's "Twelfth Five-Year Plan" Outline outlines a blueprint for accelerating the development and development of 7 strategic emerging industries such as China's high-end equipment manufacturing and new energy industries, and also accelerates the development of China's valve industry as soon as possible to get rid of the high temperature and pressure. Valves such as key devices rely mainly on imports to provide opportunities.

As a universal component, valves are also an indispensable part of major technical equipment. Especially in power, petrochemical, metallurgy, fertilizer, environmental protection, and urban water supply and drainage systems, valves play a key role in fluid control. It works, and its amount is very large.

The urbanization process in China has led to large-scale infrastructure construction throughout the country, a large number of water supply and drainage projects, especially large-scale sewage treatment projects. Water treatment equipment manufacturing industries including pipelines and valves have formed a strong water industry. The valve product should also change its performance and parameters according to the changes in the equipment application field. Current urban construction systems have gradually shifted from low-pressure iron gate valves used in the past to eco-friendly rubber sheet valves, balancing valves, metal-sealed butterfly valves and hermetic butterfly valves. In addition, as China's energy development efforts have increased, China has now become the largest country in the world with ultra-supercritical units. Large-scale, high-pressure safety valves and pressure-reducing valves must be used for the large-scale development of power stations. At the same time, valves must be opened and closed quickly. Therefore, steam traps must be developed and developed to subcritical and supercritical high parameters. Metallurgical equipment manufacturing also requires a large number of high-temperature, high-pressure valve devices. All these provide good opportunities for the development of the valve industry in China. It can be seen that the demand for the valve market in China during the “Twelfth Five-Year Plan” period has great potential for development.

At present, China has the largest number of valve companies in the world. There are more than 6,000 valve companies of all sizes, of which about 900 are valve companies with an annual output value of more than 5 million yuan. From the product point of view, China's valve industry has now been able to produce more than 10 categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, Traps, emergency shut-off valves, etc., the maximum operating temperature of 570 °C, the minimum operating temperature of -196 °C, the maximum pressure of 600 MPa, the maximum diameter of 5350 mm. According to relevant statistics, China's annual valve market turnover is as high as 50 billion yuan, but more than 100 billion yuan of the market is occupied by foreign valve companies, especially high-temperature, high pressure and other key device valves rely mainly on imports.
