High-performance brass valve solutions tailored for precision control, energy distribution, and heating networks.
Why unrestricted fluid passage is critical for high-efficiency modern piping and industrial networks.
In municipal water systems, commercial heating networks, and high-flow industrial lines, energy efficiency and fluid behavior are highly dependent on the choice of piping accessories. A Full Bore Valve (also known as a full port valve) features a spherical bore that is identical in diameter to the inside of the connecting pipeline. Because there is no narrowing of the internal diameter, flow resistance is minimized, keeping the flow coefficient (Cv) at its absolute maximum. This design is highly effective at eliminating localized cavitation, preventing pressure drops, and maintaining predictable flow dynamics across the system.
Compared to standard or reduced port valves, full bore configurations optimize pump power consumption. When fluid passes through a restriction, it experiences a localized velocity surge and subsequent pressure drop (known as the Venturi effect). This energy loss forces pumps to work harder, increasing electricity usage and causing mechanical stress across the system. By using precision-forged brass full bore valves, engineers can maintain laminar flow profiles, protect pipeline structural integrity, and ensure long-term stability in residential HVAC distribution loops, boilers, and drinking water setups.
Unifying heavy industrial capacity with global precision standards since 1996.
Established in the heart of China’s valve industry, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has developed a robust reputation for manufacturing high-quality plumbing valves, manifold systems, and specialized HVAC components. Our manufacturing footprint highlights a long-term commitment to quality, technological innovation, and environmentally sound production practices.
Our expansive manufacturing facility spans a total site area of over 45,000 square meters, with an actual usable floor area reaching 80,000 square meters. Inside, our operations feature over 600 pieces of advanced machinery, including 80+ specialized CNC machining units. This manufacturing capability enables us to serve global clients with precision and flexibility across North American, European, and Asian markets.
Integrating precision valves with heating, cooling, and water distribution networks.
Designed for underfloor heating networks and hydronic loops, our manifold setups and mixing shunts integrate flow meters, temperature indicators, and pressure relief valves. They maintain thermal balance, prevent cold spots, and minimize system-wide energy losses.
Our specialized brass boiler angel valves and relief systems regulate feedwater inlet and high-temperature discharge. Fitted with durable spherical spools, they deliver reliable, leak-free shut-off and thermal isolation in high-demand environments.
Air bubbles in closed hydronic loops can lead to pipe corrosion, pump noise, and heat transfer losses. Our brass venting valves automatically purge trapped air without manual oversight, helping to protect system efficiency and prevent air binding.
How our R&D roadmap is driving the next generation of brass fluid control systems.
Unlike cast valves, which can suffer from micro-porosity and internal stress fractures, Yuhuan Yongda uses modern hot-forging presses. This process shapes brass alloys under intense thermal and physical load, aligning grain structures to maximize tensile strength and eliminate structural weak points.
To meet global regulations on lead content in drinking water systems (such as NSF/ANSI 372 and EPA mandates), our research team has expanded the use of lead-free and low-lead brass alloys (such as CW617N and DZR brass). This ensures compliance without compromising corrosion resistance or machinability.
The Cokaren brand is driving innovation in smart heating solutions by combining physical manifolds with intelligent digital control systems (smart thermostats like model Y9031). This allows real-time monitoring and flow adjustment based on local sensor feedback, leading to more responsive energy use.
Cokaren, a specialized brand under Yuhuan Yongda, was created to deliver refined product aesthetics, close tolerance quality control, and responsive customer service.
"Keep flowing, keep warming. We design water system components with the goal of bringing consistent comfort, thermal efficiency, and safety into homes and industrial spaces worldwide."
Cokaren continues to build on this strategy, focusing on active market expansion, responsive customer support, and robust quality control as we grow toward becoming a recognized global brand.
To maintain a stable presence in North American and European markets, Yuhuan Yongda Fluid Control has established and verified comprehensive management and safety frameworks.
