In 2007, the Chinese valve core industry experienced remarkable growth, as highlighted by the statistics from the 24 major manufacturers affiliated with the China Chemical Industry Equipment Association. Output value, sales revenue, and foreign exchange earnings from exports all saw significant increases, marking a historic high for the sector. China has now firmly established itself as the leading global manufacturer in the valve core industry, exerting considerable influence over international market conditions.
According to the data, the combined sales revenue of the 24 key valve core companies reached 2.075 billion yuan, representing a 33.8% year-on-year increase. During the same period, production of valve nozzles rose to 1.707 billion sets, up 45.6%, while valve core output climbed to 2.004 billion sets, an increase of 21.8%. Based on these figures, the total sales revenue of the entire valve core industry is estimated to have reached 3.01 billion yuan, with a total output of 230,000 units and 2.45 billion valve cores produced.
Among the surveyed companies, only a few reported a slight decline, while the rest saw sales revenue increases of more than 20%, with several companies—such as Jiangyin Innovative Valves Co., Ltd., Hangzhou Wanmeng Doors Co., Ltd., Shunde Anchi Industrial Co., Ltd., and Ningbo Ouya Daocheng Auto Parts Industrial Co., Ltd.—reporting growth rates exceeding 40%. The overall production and sales ratio remained strong, with most companies achieving over 95%.
Beyond traditional valve manufacturing, many firms expanded their product lines by leveraging valve manifolds, diversifying their development strategies. For instance, Jiangyin City Innovation Group started with valves and later diversified into rubber, pads, cords, tire wires, and chemical raw materials, becoming a supplier of tire frame materials. Similarly, Shanghai Baolong and Ningbo Siming expanded into exhaust pipes and counterweights, positioning themselves as auto parts suppliers. Hangzhou Wantong developed barometers, pneumatic tools, and quick connectors, focusing on pneumatic products. These expansions not only broadened their own offerings but also contributed to the advancement of the broader valve industry.
The statistical results reveal that the overall strength of China’s valve core industry has undergone a significant transformation, reflected in three key areas. First, export capabilities have improved dramatically. In 2007, the 24 enterprises earned 872 million yuan in foreign exchange, a 21.9% increase compared to the previous year. When including two Taiwanese-funded enterprises, Six Hui and Xia Hui, the total export value of valve cores exceeded 1.38 billion yuan. According to Wang Lin, deputy director of the valve core professional committee, China's valve core output accounted for about 70% of the world total, with several companies becoming qualified automotive component suppliers.
Second, the technological innovation capabilities of Chinese valve core enterprises have significantly strengthened. Most companies have transitioned from manual to automated production, replacing instrument lathes with automatic ones and upgrading vulcanization equipment to computer-controlled systems. Additionally, investment in research and development increased, with over 80 million yuan allocated for technological upgrades in 2007. The industry also achieved a breakthrough in independent intellectual property, with approximately 40 new patents filed.
Third, company profitability has seen a substantial rise. Most enterprises reported significant profit growth compared to the previous year, with no company suffering losses. This positive trend has led to many businesses investing in land purchases, building new facilities, and upgrading equipment, creating a favorable business environment. (Chen Weifang)
