Yongda
High-durability forged brass valves and fitting assemblies built for critical HVAC and industrial pipeline integrations.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved into one of the most prominent, specialized plumbing valve manufacturers in China's prestigious "Valve Capital" – Yuhuan, Zhejiang. With a dedication to engineering excellence, our comprehensive business scope integrates advanced custom product design, prototyping, metallurgy testing, mass manufacturing, and world-class OEM/ODM sales networks.
Our premium product catalog specializes in mid-to-high-grade brass valves, hydronic fittings, and advanced HVAC distribution systems. By prioritizing metallurgical purity, environmental compliance, and high-performance sealing mechanisms, our systems are highly sought after by commercial procurement departments and mechanical systems designers across North America, Europe, and globally.
Under our advanced quality development roadmap, we introduced the Cokaren brand. Rooted in the core promise of "keep flowing, keep warming", Cokaren concentrates on refined fluid control aesthetics, leak-free operational security, and intelligent room comfort accessories designed for modern hydronic networks.
Understanding the structural integrity, pressure containment capabilities, and grain-refinement benefits of forged fluid control components.
Our forged ball valves are manufactured using hydraulic press machinery that compresses solid brass billets (such as lead-free or DZR CW617N alloys) under extreme thermal parameters. This process eliminates internal porosity, voids, and gaseous pockets that typically form during the cooling phase of casting.
Industrial fluid networks demand rigorous performance profiles. As an OEM manufacturer, Yuhuan Yongda delivers customizable forged ball valves designed for temperature margins ranging from -20°C up to 150°C, with pressure ratings spanning PN16 to PN40.
Decentralized hydronic manifolds, balancing groups, and primary mechanical plant controls engineered for residential and commercial infrastructure.
Global environmental targets require high-efficiency energy distribution platforms. Hydronic underfloor heating, central district heating networks, and mechanical cooling structures require exact heat metering and system balancing.
Yuhuan Yongda supplies a complete suite of solutions engineered to prevent system degradation and reduce energy consumption. By integrating differential pressure bypass units, high-grade brass air separators, thermostatic mixing stations, and micro-filtration strainers directly into the primary loops, system designers can prevent debris build-up and cavitation while maintaining hydronic balance.
Our engineered assemblies, featuring high-quality corrosion-resistant alloys, ensure decades of worry-free operation even in complex chemical-water treatment environments typical of modern heating and cooling plants.
The first line of defense in domestic water sanitation, designed to filter out 98% of particulate impurities in the pipeline network.
Controls the cold and hot water cycles in high-demand domestic boilers, utilizing a high-density spherical brass spool.
Vents pockets of accumulated gas in heat pump and water heater loops to prevent air locks and ensure thermodynamic stability.
Precisely regulates water temperatures by blending hot and cold supply lines, protecting piping arrays from thermal shock.
Aggregates zoning sensors to adjust multi-room HVAC manifolds, maintaining localized comfort levels via intelligent control loops.
Filters particulate micro-impurities, manages zone isolation, and tracks temperature and water pressures simultaneously.
Distributes hydronic flow balancing to individual sub-circuits, coordinating with zone valves for modular heating control.
Leveraging state-of-the-art smart manufacturing, automated tooling, and integrated raw material sourcing to safeguard project timelines.
With a sprawling manufacturing footprint exceeding 45,000 square meters (expandable to 80,000 square meters usable floor space), our plant utilizes over 600 pieces of advanced production and testing apparatus, including 80+ dedicated specialized high-precision machine tools. This scale enables us to run high-volume, multi-track orders without sacrificing dimensional stability or lead times.
Implementing lean manufacturing methodologies, Yuhuan Yongda establishes multi-tier testing parameters. From spectrographic analysis of incoming raw brass bars to 100% pneumatic leak testing (conforming to the "Fine work, no leakage" quality mandate), each valve is assigned a laser-etched heat number for comprehensive traceability.
Located near Ningbo and Shanghai shipping ports, we streamline global freight procedures. Our deep partnerships with custom brokers and international logistics agencies prevent port hold-ups, providing stable freight rates and reliable Delivery Duty Paid (DDP) or FOB supply chain options.
As global energy systems transition to smarter, low-carbon models, Yuhuan Yongda is continuously investing in next-generation fluid control technologies. Our R&D team focuses on two primary development fronts:
Operating under world-class regulatory standards to assure absolute compliance in challenging regions.
Yuhuan Yongda operates under a robust quality matrix. Our production sites maintain full certifications for ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health & Safety). This ensures that every phase of manufacturing meets strict global standards.
Our products carry CE certifications for European pressure equipment directives. We manufacture utilizing certified lead-free copper blocks to fulfill North American Safe Drinking Water Act requirements, preventing heavy metal migration in municipal potable water networks.
We provide complete localized engineering support, including 3D CAD modeling, FEA mechanical stress simulation files, and detailed localized documentation (material certificates EN 10204-3.1, pressure test results, etc.) to streamline regional client approvals.
Structuring strategic OEM contracts to maximize margin, secure continuity of supply, and control total cost of ownership (TCO).
For enterprise-level buyers, purchasing ball valves involves assessing more than just the piece-price. A thorough cost calculation must weigh freight rates, quality defect liabilities, system-down costs, and inventory holding expenses. Yuhuan Yongda works closely with global sourcing teams to minimize risks and optimize Total Cost of Ownership through:
By hedging copper futures and maintaining raw material stockpiles, we shield our clients from sudden market commodity price fluctuations, keeping pricing structures stable.
Through our OEM/ODM design process, we can build custom valves with built-in strainers, bypass channels, or monitoring ports, combining multiple individual pipeline parts into single forged units to lower assembly costs.
We offer scheduled blanket release agreements and maintain safety stocks in regional distribution hubs, protecting against shipping bottlenecks and supporting just-in-time project deliveries.
Our organization operates under a unified growth code: Struggle, Enterprising, Pragmatic, and Innovative. With "Customer first, Quality based" as our core principle, we strive to build a motivating environment for our workforce, continually improving worker benefits and development opportunities while ensuring our clients receive top-tier products.
