China ranks first in the world in the number of valve companies

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. Butterfly valve products should also change their performance and parameters according to the changes in the field of equipment applications. 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 turnover in the valve market is as high as 50 billion yuan, but more than 100 billion yuan of its market is occupied by foreign valve companies, especially high-temperature, high-pressure and other key device valves rely mainly on the import of China's valve industry as soon as possible Get rid of high temperature, high pressure and other key devices high-performance butterfly valve mainly dependent on the import situation? The reporter learned that China’s valve market is a “cake”, but the market competition is fierce. Since the valve is a product with a very low profit rate, although the market price of the valve rises and falls year by year, the range is small and the overall situation is relatively stable. The valve manufacturers basically follow the valve industry reference price compiled by China General Valve Industry Association. Pricing. Due to fierce market competition, some valve manufacturers are still implementing their prices in 1996 to win over customers; others also consider the cost of using raw materials for castings and forgings, preferring to use blanks from small and medium-sized steel mills and discarding them. The quality of the large steel billets has led to a poor product quality. At present, the leading products of pneumatic butterfly valve companies in our country are still low quality ordinary products. In addition, various valves produced by domestic companies have the disadvantages of external leakage, internal leakage, poor appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the 1980s. The early international level. In addition, China's valve industry has a large gap with foreign companies in terms of industrial structure and industry specialization.

Due to such a large gap, it is not surprising that China's valve industry will have more than 10% of the market occupied by foreign companies. A related person of the China General Machinery Industry Association Valve Subcommittee believes that to change this situation, improving valve quality is the key.
