Request QuoteSingapore stands as one of the world's most sophisticated infrastructure hubs, prioritizing structural sustainability through strict building regulatory codes. The Public Utilities Board (PUB) enforces rigorous guidelines for water fittings (such as SS 375 and SS 270) to ensure zero lead contamination and long-term durability. In this environment, stop valves serve as critical security barriers, isolating fluid lines during system updates without shutting down multi-story operations.
With Singapore's Green Mark certification scheme pushing commercial buildings to cut energy use, mechanical engineers are increasingly adopting integrated HVAC systems. In these configurations, high-performance stop valves, differential pressure bypass valves, and air release valves work together to maintain optimal flow rates. This optimization protects building chillers from dynamic thermal stresses and significantly lowers energy consumption.
Furthermore, Singapore's maritime, offshore, and petrochemical industries in Jurong Island require rugged components that resist dezincification (DZR) and mechanical fatigue. Using inferior grade valves leads to costly downtime and safety risks. Our brass valves, designed with high-density forged brass (such as CW617N or HPb59-1), offer structural integrity that meets these demanding commercial and industrial requirements.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is located in the "China Valve Capital"—Yuhuan, Zhejiang. As a professional plumbing valve manufacturer, we specialize in the design, development, production, and sale of mid-to-high-end brass valves, fittings, and HVAC systems.
Our expansive manufacturing campus spans a factory area of over 45,000 square meters, with an actual usable area reaching 80,000 square meters. Equipped with over 600 sets of advanced manufacturing and testing devices—including more than 80 specialized multi-axis machine tools—we offer the technical capability and volume flexibility needed to meet international engineering specifications.
To better serve premium residential markets, we introduced our Cokaren brand. Rooted in the promise of "keep flowing, keep warming", Cokaren focus on delivering refined appearance, reliable quality, and environmentally conscious water system accessories designed for long-term home comfort.
Our specialized product line is engineered to optimize water quality, pressure control, and temperature management within modern district cooling and heating networks.
The first line of defense in domestic water sanitation, filtering 98% of impurities in the pipeline.
Controls cold and hot water flow in boiler systems, featuring a high-durability spherical spool.
Discharges trapped air from heat pumps and water heaters, preventing air locks and system cavitation.
Blends hot and cold water supplies to stabilize temperatures and protect downstream piping networks.
Integrates control of multiple HVAC units to maintain consistent room temperatures.
Filters piping impurities, controls manifold loops, and measures system temperature and pressure.
Yuhuan, Zhejiang, is recognized globally as the industrial hub for brass valves and plumbing fixtures. This concentrated manufacturing ecosystem enables rapid prototyping, streamlined material sourcing, and efficient production scaling. At Yuhuan Yongda, we combine this regional logistical advantage with rigorous in-house quality control.
Our production workflow is vertically integrated—from hot forging and precision machining to automated surface finishing, assembly, and pressure testing. Every production run undergoes spectrographic testing to verify chemical composition, alongside air and water pressure testing to ensure zero-leakage performance. Operating under ISO 9001-2015, ISO 14001-2015, and ISO 45001-2018 certifications, we maintain high standards across all stages of production.
Through our dedicated R&D department, we continuously refine our tooling and metal alloys. This commitment ensures our valves comply with international certifications, including NSF, CE, and WRAS, supporting projects in Singapore and global export markets alike.
Global regulations are shifting toward low-lead and lead-free brass (e.g., CW617N, CW602N DZR brass). These alloys prevent heavy metals from leaching into municipal water lines, ensuring compliance with strict environmental health standards.
Smart commercial buildings require integrated telemetry. Combining brass manifolds with motorized shut-off actuators and LCD smart thermostats enables automated zone control and optimized flow distribution.
Our quality assurance program emphasizes double O-ring stem designs alongside virgin PTFE valve seats. This structure stands up to high cycling frequencies and thermal fluctuations, keeping systems leak-free.
Engineered for precise fluid throttling and isolating. Features robust handwheel configuration.
