Explore our high-performance brass safety valves, manifolds, and press fittings engineered for extreme operational integrity.
Modern commercial and industrial water systems demand unprecedented levels of performance, efficiency, and zero-defect quality. With changing environmental directives, specifically in North America and Western Europe, the need for robust plumbing brass valves (PBV) that offer lead-free options, dezincification resistance (DZR), and microstructural density has intensified. High-grade brass components act as the foundational grid in modern district heating, potable water distribution, and HVAC balancing system architectures.
As the demand for energy efficiency intensifies globally, thermal energy management systems, manifolds, mixing valves, and pressure-balanced solutions must operate dynamically. Standard brass casting is no longer sufficient. Precision hot forging combined with high-accuracy CNC machining ensures that systems can endure wide fluctuations in water hammer pressures, chemical disinfection compounds, and extreme thermal cycling. Operating as a major cornerstone in the plumbing Capital of Yuhuan, China, manufacturers like Yuhuan Yongda Fluid Control Co., Ltd. integrate advanced thermodynamics and metallurgical technology to manufacture high-tier PBV components destined for high-demand international markets.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is a premiere developer and manufacturer of brass valves, fittings, and advanced HVAC components.
Founded in 1996, and situated strategically in "China Valve Capital" – Yuhuan, Zhejiang, Yuhuan Yongda has evolved into a powerhouse of professional fluid control engineering. Our enterprise coordinates product design, CAD/CAE development, hot-forge production, CNC machining, rigorous multi-stage pressure testing, and professional global sales.
Our product lineup addresses three core categories: brass valves, pipeline fittings, and custom HVAC products. Geared toward middle-to-high-grade segments, our products feature premium environmental protection attributes, engineered lead-free and dezincification-resistant alloys. This ecological and engineering approach has made our components the preferred choice for consumers and engineers across North America, Europe, and other highly regulated global markets.
Operating a massive factory footprint exceeding 45,000 square meters, with an actual operational area reaching over 80,000 square meters, our facility hosts more than 600 sets of advanced manufacturing and testing devices. This includes more than 80 sets of specialized, high-precision automated machine tools. Armed with these advanced assets, we satisfy complex custom specifications and export quality HVAC/plumbing equipment to more than 20 countries worldwide.
Engineering future-proof solutions optimized for regional environmental regulations, HVAC structures, and smart infrastructure.
Adhering to NSF/ANSI 61 and NSF 372 lead-free standards is essential for potable water. Our PBV products utilize optimized silicon-brass and bismuth-brass formulations that guarantee heavy-metal compliance while preventing dezincification in highly acidic soft-water systems.
For high-density municipal heat grids across Germany, Poland, and Scandinavia, our brass thermostatic radiator valves and manifolds manage constant-differential hydraulic pressure, optimizing heat flow distribution and decreasing energy usage by up to 22%.
Future HVAC frameworks rely on automated sensors. Our technical roadmap incorporates digital, thermal, and electro-actuator valves compatible with smart thermostats, facilitating zone-based temperature tuning in high-occupancy residential and commercial buildings.
