Premium brass valves, smart manifolds, and HVAC distribution components designed for zero-leakage, high-durability performance.
Originating in Yuhuan, Zhejiang—widely recognized as the "China Valve Capital"—Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved over 25+ years into a premier high-density manufacturing enterprise. We integrate advanced structural product design, metallurgical testing, specialized machining, and global exporting services under one unified, quality-driven operation.
Our product lines focus primarily on high-precision brass valves, heavy-duty pipe fittings, and sophisticated HVAC distribution systems. Engineered strictly for middle-to-high-grade market sectors, our equipment highlights key performance characteristics including high-temperature resilience, eco-friendly alloy compositions, and zero-leakage profiles. This has made our solutions highly preferred by commercial engineers and infrastructure contractors across North America and Europe.
Cokaren, our high-tier consumer-industrial brand, represents refined tolerances, pristine surface finishes, and smart-thermodynamic control. Our engineering focus centers on creating water systems and underfloor heating controls that bring thermal efficiency and environmental stability to modern green homes and smart buildings.
Deploying digital manufacturing loops to ensure continuous output stability and quick-turn custom OEM/ODM delivery.
How mechanical design, eco-regulation compliance, and structural engineering are redefining global valve sourcing.
With strict standards such as NSF/ANSI 372 and European lead limits, global OEMs are moving towards CW617N, CW602N (Dezincification Resistant), and lead-free bismuth/silicon-brass formulations. Our advanced melting and casting systems guarantee precise control over chemical composition, ensuring compliance with strict environmental regulations.
Modern hydronic heating systems demand real-time pressure diagnostics, automatic balancing, and electronic modulation. By combining mechanical crane ball valves with thermostatic actuators and differential bypass manifolds, we offer complete subsystems that interface directly with building management systems (BMS).
In commercial gas, boiler, and district steam setups, minor leaks can lead to system failures. Our manufacturing process uses double O-ring stem seals in Viton/HNBR, coupled with PTFE seats containing specialized carbon-fiber reinforcement. This configuration provides bubble-tight shut-off across high pressure cycles.
With an actual usable floor area reaching 80,000 square meters and more than 600 sets of advanced production and testing equipment (including 80+ specialized multi-axis CNC machine tools), we have transitioned to semi-automated manufacturing. This integration ensures that every single batch of brass manifolds or high-pressure ball valves meets precise dimensional specifications.
Our advanced metallurgical testing includes optical emission spectrometers to analyze raw materials, along with custom 3D coordinate measuring machines (CMM) to verify tight tolerances. To maintain supply chain resilience during demand surges, our digital warehouse management system tracks and schedules everything from raw brass bar extrusions to finished surface nickel plating.
This infrastructure minimizes production delays, ensuring our global distribution partners receive consistent quality, reliable delivery timelines, and direct cost efficiencies.
Proven reliability across diverse industrial, commercial, and residential water distribution networks.
Our boiler angle valves and high-flow brass ball valves manage cold-to-hot water cycles under extreme pressures. They prevent water hammer and provide dependable isolation, keeping thermal loop networks running smoothly.
Our precision brass manifolds distribute water flow evenly across multi-zone residential zones. Combined with thermal actuators and mixing shunts, they enable responsive energy-saving temperature regulation.
Integrating filters directly into the ball valve body helps capture line debris, protect down-stream heat exchangers, and maintain system cleanliness in commercial plumbing circuits.
Our facility operates under a rigorous international quality framework. We have passed and maintained ISO9001-2015 (Quality Management System), ISO14001-2015 (Environmental Management System), and ISO45001-2018 (Occupational Health and Safety Management System) certifications.
These certifications verify that our engineering, chemical handling, and employee work standards meet international protocols. They provide global buyers with confidence in the safety, quality, and origin of our products.
