China's valve industry needs to work hard to seize the international market
At present, about 10% of the valve industry in China is occupied by foreign companies. The relevant person of the valve branch of China General Machinery Industry Association believes that to change this situation, improving valve quality is the key.
Valves occupy a considerable proportion in mechanical products. According to statistics of foreign industrial countries, the output value of the valve is the sum of compressor, fan and pump, accounting for 5% of the total output value of the entire machinery industry. At the same time, as an important part of major technical equipment, especially in the power, petrochemical, metallurgy, urban water supply and drainage systems, valves play a key role, and they are used in large quantities.
At present, there are about 6,000 valve companies in China, of which 900 have an annual output value of more than 5 million yuan. There are 3 domestically listed valve companies, namely China Nuclear Technology, Hongcheng Shares, and Guangdong Pearl. Last year, CNNC’s main business income was 235 million yuan, Hongcheng's main business income was 146 million yuan, and Guangdong Pearl's main business income was 150 million yuan. These companies, no matter their scale or product quality, are unable to compete with similar foreign companies.
Analysis of the industry, resulting in the current passive reasons for our valve market, there are two main reasons: First, there is still a gap between domestic valve products and imported products, the quality needs to be improved; Second, some users do not have a strong sense of localization, and even artificially set the threshold This makes it difficult for domestic companies to win bids when competing with foreign companies.
Relevant experts believe that the current production of various valves in China's enterprises generally have the drawbacks of external leakage, internal leakage, appearance quality is not high, short life, inflexible operation and valve electrical devices and pneumatic devices are not reliable, some products are only equivalent to The international level of the early 1980s. Therefore, the development of the valve industry urgently requires the development of new products with high technological content.
Relevant experts demand that the valve industry should vigorously adopt international standards and foreign advanced standards, strictly implement existing national standards, reform existing products, and make the updated products reach the international level in the 1990s. At the same time, the valve industry should take effective measures for the selection of raw materials for castings and forgings, casting processes, forging processes, and heat treatment, so that the quality of castings and forgings and the quality of appearance can reach international standards.
On the other hand, it should continue to carry out internal and external leakage research, strict mechanical processing technology, and vigorously promote new types of sealing materials, improve the accuracy of key parts of the product processing, extend product life, so that the valve "a short two leakage" phenomenon fundamentally improved.
Established in 2000, Fengquan Valve Co., Ltd. is a high-tech enterprise located in Oubei, a hometown of pumps and valves. The company mainly produces multi-functional pump control valves, hydraulic control valves, soft seal gate valves, hard seal butterfly valves and other 15 series of various specifications of the valve products, widely used in municipal water supply, sewage treatment, petrochemicals, iron and steel metallurgy and other industries for water supply and drainage Or fluid control system, with an annual production capacity of 80 million.
When the company was founded, the starting capital was only 500,000 yuan, and the annual production value was less than 800,000 yuan. In 2004, the company had developed a production value of 50 million yuan and taxed 5.88 million yuan. The secret of this company's success is because of its core manufacturing and core technology development capabilities, strong professionalism, and high technical content. The company developed and developed a multi-functional pump control valve with independent intellectual property rights to fill the gaps in the domestic, technical level at the leading domestic level, has 12 patents, has won 7 provincial and ministerial level scientific and technological progress awards. The company has also edited three industry standards such as diaphragm type quick-opening mud discharge valves. The products have been incorporated into nine national and industrial standards. They are the companies with the largest nominal diameter and highest nominal pressure in the production of hydraulic control valves in the valve industry.
Looking at the domestic valve market, the valve industry has a wide range of development space. According to relevant experts' forecasts, the future market of valves is mainly in the power industry, petrochemical industry, fertilizer, environmental protection and urban construction industries. They asserted that whoever has good technology, who has excellent quality, and who can continuously develop new products, whoever can seize the initiative and stand out in the fierce market competition.

The market of LNG (Liquefied Natural Gas) is booming worldwide during the past years. The transportation of LNG over long distances, generate a great demand of cryogenic pipeline facilities, including cryogenic valves.
Due to high performance of the cryogenic valves, materials with outstanding mechanical properties in crygenic environments are required. The body and trim materials should pass the impact test at a specific temperature. Other designs also include: extended bonnet to make sure the temperature of stuffing box remains at a relative higher interval; relief port or by-pass system to prevent abnormal pressure rising which could destroy the pipe facilities; etc.
Kolink cryogenic valves (low temperature valves) include: crygenic gate valves, crygenic globe valves, crygenic check valves and crygenic ball valves, with material range of LCB, LF2, LC1, LC3, 304, 316, and temperature range of -46 ~ 196°C.
