There are two major valve and valve bases in Wenzhou, the first is the "Hometown of Chinese Pump Valves" in Oubei Town, Yongjia County, and the other is the "China Valve City" in Longwan District. According to Huang Zuoxing, president of the Wenzhou Pump Valve Association, the Wenzhou valve industry accounts for 37% of the domestic market. Its growth is mainly achieved through the development of new products, increasing the technological content of products, and continuously innovating and improving the added value of products. In particular, in recent years, the Wenzhou valve industry has completed a number of national key new product prototypes such as the National Torch Program project for the development of the largest caliber ball valve in China, ultra-short valves, and valves in the nuclear field.
As one of the leading enterprises in the Wenzhou valve and valve industry, the Xuanda Group has developed a low-temperature sulfuric acid heat recovery system that fills the gap in the country and is now on the market. It is expected that the annual output value of this product will be 200 million yuan. Zhejiang Huadong Valve Co., Ltd. has successively developed high-temperature and high-pressure double-self-sealing sealed gate valves and high-precision valves used in nuclear power plants in recent years. It also successfully developed the first hydrogenation valve and ethylene valve in China, rewriting all the domestic hydrogen refueling valves relying on imports. history. This year, Huadong Valve has two other products listed as "National Torch Plan Project" and "National Key New Product". Since the Bertley Group began to invest heavily in scientific and technological innovation in 2003, its R&D investment has accounted for 5% of sales revenue in 2006. Since Wenzhou Tengyu Pump & Valve Manufacturing Co., Ltd. established a long-term cooperative relationship with the Fluid Machinery Engineering Research Center of Jiangsu University in 2005, it has been able to guarantee the development of more than two new products every year. Up to now, Wenzhou has a number of pump and valve companies have become first-tier suppliers of PetroChina and Sinopec.
On April 12th this year, Yongjia officially launched the industrial upgrade plan. The Bank of China Wenzhou Branch will arrange for 2 billion yuan to help Yongjia solve the bottleneck in the development, which will effectively support the upgrade and development of the Yongjia valve industry. In addition, at present, Wenzhou Pump & Valve Enterprise is actively conducting “introducing internal outreachâ€. While actively introducing high-level talents, it also strengthens cooperation with professional institutes and domestic and foreign counterparts. In 2006, Wenzhou Municipal Government, Yongjia County Government and Lanzhou University of Technology established the Pump Valve Engineering Research Institute “in hand†to enhance the traditional industries of Wenzhou Pump Valve. Yongjia County Pump & Valve Technology Innovation Service Center cooperates with 8 universities including Lanzhou Polytechnic University, Changsha University of Science and Technology, Sichuan Panzhihua University, Wenzhou Vocational and Technical College, Wuhan Vocational and Technical College, and has established specialized talents for 300 years. More than one name. It is this growing atmosphere of innovation that has vigorously promoted the rapid development of the Wenzhou valve industry. In the first three quarters of this year, the total output value of the Wenzhou valve and valve industry reached about 18 billion yuan, maintaining a year-on-year growth rate of more than 25%. The total annual export value of this year is expected to exceed 400 million U.S. dollars.
Recently, the nuclear power electric gate valve manufactured by Zhejiang Huadong Valve Co., Ltd. passed the acceptance and was shipped to Pakistan for the second phase of the Chashma nuclear power plant in the country. This is the first time that Wenzhou Valve has entered the international nuclear power plant project. It is understood that due to the general emphasis on scientific and technological innovation of enterprises, the proportion of large-diameter valves with high technological content in the Wenzhou valve industry accounts for more than 60% of export products. Relying on a sound industrial policy and an innovative environment, Wenzhou Valve is showing promising changes from low-end to high-end development, from general fields to petrochemical, nuclear power and other specialized fields.
