In 2007, the Chinese valve core industry witnessed remarkable growth in key economic indicators, as reported by the China Chemical Industry Equipment Association. The output value, sales revenue, and foreign exchange earnings from exports all experienced significant leaps. This period marked a historic high for the sector, with China firmly establishing itself as the leading global manufacturer of valve cores and exerting direct influence over international market conditions.
According to the data, the combined sales revenue of the 24 major valve core companies reached 2.075 billion yuan in 2007, representing a 33.8% increase compared to the previous year. During the same period, the production of valve nozzles rose to 1.707 billion units, an impressive 45.6% year-on-year growth, while valve core production reached 2.004 billion units, up 21.8%. Based on these figures, the total sales revenue of the entire valve core industry is estimated to have surpassed 3.01 billion yuan, with total valve output reaching 230,000 units and valve core output at 2.45 billion units.
Among the surveyed companies, only a few saw a slight decline, while the rest experienced varying degrees of growth, most of which exceeded 20%. Notably, several firms, including Jiangyin Innovative Valves Co., Ltd., Hangzhou Wanmeng Doors Co., Ltd., Shunde Anchi Industrial Co., Ltd., and Ningbo Ouya Daocheng Auto Parts Industrial Co., Ltd., achieved growth rates above 40%. Overall, the production and sales ratio remained strong, with most companies achieving over 95%.
Beyond their success in the valve industry, many companies expanded into related fields such as valve manifolds, diversifying their product lines. For example, Jiangyin City Innovation Group expanded from valves into rubber, pads, cords, tire wires, and chemical raw materials, becoming a supplier of tire frame materials. Similarly, Shanghai Baolong and Ningbo Siming focused on exhaust pipes and counterweights, positioning themselves as auto parts suppliers. Hangzhou Wantong developed barometers, pneumatic tools, and quick connectors, aiming to become a leading provider of pneumatic products. These expansions not only broadened their business scope but also contributed to the advancement of the valve industry as a whole.
The statistical results highlight a substantial improvement in the overall strength of China’s valve core industry, reflected in three main areas. First, the ability to generate foreign exchange through exports significantly increased. The 24 enterprises reported total foreign exchange earnings of 872 million yuan in 2007, a 21.9% rise from the previous year. Including two Taiwan-funded enterprises, 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 reached approximately 70% of the world's total, with several companies becoming qualified suppliers for automotive components.
Second, the technological innovation capabilities of Chinese valve core companies have strengthened. Most companies have transitioned to automated production, replacing traditional lathes with automatic ones and upgrading vulcanization equipment to computer-controlled systems. Additionally, investment in research and development has increased. In 2007 alone, more than 80 million yuan was invested in technological upgrades and development. The industry also saw a shift in intellectual property rights, with around 40 patents granted, marking a significant step forward.
Third, profitability across the sector improved dramatically. Most companies reported substantial profit increases compared to the previous year, with no firm experiencing losses. This positive trend led to many companies investing in land purchases, building new facilities, and upgrading equipment, creating a favorable business environment.
