Specially adapted high-performance fittings designed to withstand the unique water chemistry and thermal demands of Central Asian municipal projects.
Uzbekistan is undergoing a historic construction and municipal upgrade cycle. Driven by government-backed housing expansions, new smart city designs in Tashkent City, and modernized gas and hot water grid updates in historic urban centers like Samarkand and Bukhara, the demand for reliable and long-lasting piping networks has reached unprecedented levels.
Local installation projects deal with extreme continental temperature differentials ranging from sub-zero winters (-20°C) to scorching desert summers (+45°C). This severe thermal cycling puts intense structural strain on piping systems. Substandard plastic fittings or low-grade recycled alloys degrade rapidly, leading to major leaks and costly line failures. Our heavy-forged dezincification-resistant (DZR) brass fitting series provides the optimal mechanical strength, corrosion prevention, and metallurgical integrity required for the modern Central Asian landscape.
Many urban areas across the Fergana Valley and Karakalpakstan present highly mineralized municipal tap water. Standard brass components are vulnerable to dezincification under these conditions. Our CW617N and HPb59-1 forged brass fittings utilize advanced metallurgical configurations that prevent alloy breakdown, ensuring a service life exceeding 50 years.
Leveraging over 28 years of advanced fluid control engineering, Yuhuan Yongda Fluid Control Co., Ltd. delivers high-precision systems to global target markets.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was established in 1996 in Yuhuan, Zhejiang—the renowned "China Valve Capital." We operate a state-of-the-art facility utilizing more than 600 sets of advanced manufacturing and testing equipment, including 80+ specialized custom machine tools. With our massive 45,000 m² footprint (80,000 m² actual usable space), we supply top-tier residential valves, manifold accessories, and HVAC piping products globally.
Under our premium brand, Cokaren, and our core promise "keep flowing, keep warming," we design, develop, and test high-grade fluid control components. Every batch is manufactured to meet demanding European and American standards, guaranteeing seamless compatibility with Uzbekistan's local municipal networks.
Our specialized product variants meet the demanding requirements of various sectors in Central Asia.
Tashkent and regional administrative hubs are heavily shifting toward premium hydronic underfloor heating. Our multi-port manifolds and mixing shunt valve groups stabilize building water distribution, ensuring temperature control across variable flow rates.
For orchard irrigation in the Fergana and Namangan regions, our heavy-duty hose bibcocks, garden hose fittings, and compression assemblies connect PE lines securely, preventing system pressure losses due to UV and soil degradation.
With municipal heating upgrades underway, our ASTM-compliant crimp components, automatic venting valves, and balancing solutions optimize energy transfer for central boilers and regional boiler houses.

We verify compatibility across international standards, providing threads cut to ISO 228-1 (parallel G-threads), ISO 7-1 (tapered R-threads), and NPT specifications. This guarantees leak-proof connections to existing Soviet-standard steel networks (GOST) as well as modern European-sourced multi-layer composite pipes.
Integrated hydronic and water management products configured for optimal indoor climate and safety.
Our energy distribution assemblies are designed to regulate, balance, and distribute hydronic heating throughout modern residential structures.
