Engineered Precision Flow Systems & Global Export Leader
Founded in 1996 in the heart of China’s valve capital, Yuhuan, Zhejiang, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved into a global powerhouse in the field of design, development, production, and distribution of premium brass valves, brass fittings, and specialized HVAC equipment. Focused on the middle and high-grade international markets, our products highlight the advantages of environmental protection, lead-free composition, and precise fluid dynamics.
Our commitment to excellence has positioned us as a preferred OEM/ODM manufacturer for major plumbing and HVAC distributors in North America, Western Europe, and across more than 20 countries. Under our premium brand Cokaren, we deliver on the brand promise of "Keep Flowing, Keep Warming", striving to bring thermodynamic balance and safe domestic water systems to homes worldwide.
Understanding the technical, economic, and compliance realities governing high-end brass valves in modern projects.
International commercial plumbing networks demand localized supply buffers, complete material traceability certifications, and strict dimensional tolerances to assure system integrity over decades of operation.
With North America enforcing NSF/ANSI 372 and Europe standardizing on CW617N/CW602N (Dezincification Resistant) brass alloys, our metallurgy maintains compliant thresholds under strict environmental standards.
Modern hydronic layouts dictate the integration of thermostatic control, manifold distribution, and filtration devices into a single, cohesive, dynamic flow architecture for maximum energy savings.
Our comprehensive thermodynamic component layouts guarantee thermal balance and zero leakage across domestic and industrial energy distribution systems.
Yuhuan Yongda’s system solutions are built upon optimized hydraulic pathways that reduce turbulent flow and minimize cavitation risks. Through meticulous design, we address the integration challenges faced by HVAC engineers, creating modular components that easily fit into floor heating circuits, boiler control groups, and potable water stations.
By using premium hot-forged brass techniques and specialized multi-axis machinery, every component features a high structural density. Our design policy of "Fine work, no leakage" ensures that our systems perform flawlessly under continuous thermal cycling and high fluid velocities.
The first line of defense in domestic water sanitation, designed to filter 98% of macro impurities and suspended solids in the pipeline, shielding downstream actuators and valves.
Features a specialized spherical brass spool designed to control hot and cold fluid inputs at boiler inlets, providing high-flow throughput with minimal pressure drop.
Automatically discharges accumulated air pockets in high-temperature air source heat pumps and boilers, preventing air binding and optimizing heat transfer efficiency.
A high-precision mixing station that blends hot supply and cold return water to deliver a stable, pre-set temp flow, protecting PEX pipe networks from thermal stress.
Serves as the control brain, connecting sensors, mixing systems, and zone valves to modulate ambient temperatures in multi-zone residential floor heating.
A multi-functional system valve designed to filter media, measure pressure drop, monitor real-time temperature, and control isolation at main manifold inlets.
How Yuhuan Yongda fuses raw metallurgy with automatic production to meet the quality needs of tomorrow.
Employing high-density hot forging presses to eliminate micro-porosity and internal structural flaws. CAD/CAM software validates fluid dynamics, reducing localized turbulence and valve seat wear.
Every single valve undergoes rigorous high-pressure hydrostatic and pneumatic seat testing. Our facility utilizes automated leak detection equipment, ensuring that zero-defect valves leave our plant.
Yuhuan Yongda takes pride in meeting international standards. We believe that professional management systems, workplace safety, and environmental care are fundamental components of an enduring global supply chain. Our operations conform to key industry directives:
