China's First-of-Its-Kind Breakthrough | TVI's DN2600 Flow & PressureRegulating Valve Successfully Manufactured

Tianjin Tanggu No.1 Valve Co., Ltd. (TVI), a leading enterprise in the Chinese valve industry, has independentlydeveloped and manufactured the DN2600 Flow & Pressure Regulating Valve, marking a critical milestone inthe localization of super-large diameter hydraulic control valves. As China's first-of -its-kind (L) productin this category, this breakthrough fills the technical gap in the domestic market for ultra-large flow regulatingequipment.

With a nominal diameter of 260omm, this valve integrates multiple core functions including flow regulation,pressure control, energy dissipation, and cavitation resistance. Specifically designed for major waterconservancy projects such as long-distance water transmission systems, key water control projects, andmunicipal trunk water supply networks, the valve ensures stable operation, high-precision control, and a longservice life. Its comprehensive performance has reached the international advanced level.

For a long time, super-large diameter flow and pressure regulating valves have relied heavily on imports,resulting in high costs, long lead times, and limited after-sales support. The successful development of thisdomestic product effectively breaks the foreign monopoly, significantly reduces project construction costs, andenhances the independent supply capacity of China's water infrastructure equipment. It provides keyequipment support for the national water network construction and the efficient utilization of water resources.

As a backbone enterprise in China's valve industry, Tianjin Tanggu No.1 Valve Co., Ltd. will continue to deepenits investment in technological innovation, promote the localization of more high-end valves, and contribute tothe high-quality development of China's water conservancy equipment industry.
