The day before, aerospace science and Technology Group developed six 11 high-end valve continuous production in the oil refining Market pipeline project bid. The products with better quality, lower price, shorter manufacturing cycle, more efficient customer service service, beat foreign plug valves the world's largest manufacturer, broke the monopoly in China's oil pipeline market.

Since 2008, 11 expedition companies began to plug the domestic development of research, through 6 patents, the formation of a core technology with independent intellectual property rights, the realization of China's high-end valve localization. The 11 cock valve development experience gained and technological achievements, not only can promote the similar localization of the valve, but also for the improvement of China's pipeline and petrochemical industry valve research technology has played a positive role in promoting.
