The valve is a control component in the pipeline transportation system and can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals and radioactive media. In the pharmaceutical industry, valves also play a big role.
According to statistics, there are currently more than 3,000 valve manufacturing enterprises in China that can produce gate valves, throttle valves, ball valves, globe valves, butterfly valves, diaphragm valves, control methods, etc., to meet the requirements and needs of various fields. In the context of the rapid development of pharmaceutical and other industries, the valve market is bound to usher in good development space. In terms of market share, in recent years, with the rise of the brand strength of domestic valve companies and the maturity of valve technology, the share of imported valves in the domestic market has gradually declined, and domestic valves have achieved effective substitution. According to statistical data, from January to December 2018, China's valve imports amounted to 103.997 million sets, a year-on-year decrease of 2.1%; from January to December 2018, China's valve imports amounted to 7328128 thousand US dollars, an increase of 20% year-on-year. Taking electric valves as an example, at present, domestic electric valve manufacturers are mainly concentrated in Zhejiang, Jiangsu and Shanghai. According to relevant information, in 2017, among the top 50 companies in the geographical distribution of electric valve manufacturers in China, there were 6 in Zhejiang, 4 in Jiangsu, and 6 in Shanghai. It can be seen that one third has already been localized, and this proportion is still increasing.
The improvement of the market share of domestic valves is inseparable from the improvement of the quality of electric valves. On January 3, 2019, the Anhui Provincial Bureau of Quality and Technical Supervision announced the results of the 2018 provincial-level supervision and inspection of valve products. It is reported that this time a random inspection of 10 production enterprises in four regions of Hefei, Wuhu, Chizhou and Tongling, a random inspection of 10 groups, 9 groups of samples are qualified, sampling qualification rate is 90%.
It is reported that the provincial supervision spot check is a relatively comprehensive survey of the product quality of valve production enterprises in Anhui Province, which can basically reflect the current status of valve product quality in Anhui Province. It can be seen that the quality of domestic valves can basically be guaranteed, which helps enterprises to stabilize production. In terms of valve technology, at present, many valve companies are using intelligent control processes and modern precision management to realize the deep integration of valve industry information and industrialization, and promote the better localization of China's valves.
