Zhejiang Shitong Valve Co., Ltd. is a professional manufacturer of API and Japanese standard JIS valves. The factory is located in Wenzhou Economic and Technological Development Zone, Zhejiang. Close to Wenzhou 10,000-ton wharf, Yongtaiwen Expressway and Wenzhou Airport, the geographical position is superior, water and land transportation is convenient, and it has unique advantages in development. As a high-tech enterprise integrating R&D, production and sales, the products include American standard API, ball valve, gate valve, globe valve, check valve, cryogenic valve, Y-type filter, flange and other series. After more than ten years of production and development, our company has been carrying forward the diligence, pragmatism and innovative spirit of Wenzhou people, adhering to the business philosophy of "credit-based, quality first". The comprehensive capabilities of our technology and development are constantly being strengthened. Our product diameter: 1/2"-32" DN10-DN800, pressure: 150LB-900LB; PN10-PN160; Material: WCB
Over the past 20 years, with the development of large-scale foreign complete sets of technology, a series of new sets of equipment and stand-alone machines have emerged. The development of new types of equipment related to valves is characterized by large-scale, high-parameterization, high-performance automation and complete sets. Refining equipment: 36.4 million t/year for the largest refinery (Virgin Islands in the Caribbean), 30 million t/year (Venezuela). At present, there are nearly 30 refineries with more than 20 million t/year. The processing capacity of the largest unit refinery: 24 million t/year for atmospheric and vacuum distillation units, 8.24 million t/year for catalytic cracking units, 5.69 million t/year for reforming units, and 3.2 million t/year for hydrocracking units. Oil and gas long-distance pipeline equipment: In recent years, long-distance pipelines have developed rapidly. The main reason is that the cost is low, which is only equivalent to 1/3 of railway transportation; the second is buried in the ground and not easy to be destroyed; the third is the rapid construction of pipelines and investment.
With the development of large-scale foreign complete sets of technology, a series of new sets of equipment and stand-alone machines have emerged. The development of new types of equipment related to valves is characterized by large-scale, high-parameterization, high-performance automation and complete sets, which are compatible with the control methods of these complete sets of equipment. In the past 20 years, the control methods of foreign valves have also developed greatly. In addition to general manual, motorized, electric, pneumatic, hydraulic transmission, the variety of valves for electro-hydraulic linkage, gas-liquid linkage, and automatic control is increasing, and there is a trend of further development. Such as oil refining equipment. The largest refinery is 36.4 million tons / year (Virgin Islands in the Caribbean), 30 million tons / year (Venezuela). At present, there are nearly 30 refineries with a capacity of 20 million tons/year; the processing capacity of the largest unit refinery and pressure reduction unit reaches 24 million tons/year, the catalytic cracking unit reaches 8.24 million tons/year, and the hydrocracking unit reaches 3.2 million tons/
The valve industry is an important branch of our general machinery. Its products are widely used in petroleum, chemical, metallurgy, electric power, urban construction, environmental protection and other industries as key equipment for fluid control. Currently, the valve manufacturing industry is in a very favorable development opportunity. This is because: 1. The state-owned economy continues to develop steadily. Investment in fixed assets has gradually expanded. In particular, the construction of several projects such as “West-East Gas Transmission”, “West-to-East Power Transmission” and “South-to-North Water Transfer” requires a large number of valve products. Second, with the entry of WTO, the international trade threshold is lowered and developed countries adjust product structure. China is gradually becoming the world's largest processing plant, and the trend of valve products is facing greater development. So how to seize this strategic opportunity to accelerate the development of the valve industry. Professionals in the industry have analyzed from the following aspects: 1. Actively promote joint restructuring among enterprises.
