Yongda
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was established in 1996. The enterprise is situated in Yuhuan, Zhejiang Province—widely recognized as the "Valves Capital of China." As a highly specialized manufacturing corporation, Yongda is built around a comprehensive operational framework integrating engineering design, prototype development, industrial production, and global sales channels.
The company’s portfolio is structurally categorized into three specialized sectors: Brass Valves, Precision Fittings, and HVAC Control Components. Yongda's hardware systems are strategically positioned within the medium-to-high-grade market segment, placing a major emphasis on environmental sustainability, material integrity, and long-term operating efficiency. These priorities make Yongda a reliable partner for distributors, engineering firms, and procurement networks across North America, Europe, and Asia.
Operating a manufacturing campus exceeding 45,000 square meters, with an actual usable floor area reaching 80,000 square meters, Yongda hosts more than 600 sets of advanced manufacturing and metrology systems, including 80+ specialized multi-axis machine tools. This capacity enables Yongda to satisfy the stringent requirements of diverse international standards and successfully export critical flow control solutions to more than 20 countries.
Cokaren is the newly established premium brand of Yuhuan Yongda Fluid Control Co., Ltd. It represents the company's commitment to refining aesthetic industrial design and quality control in residential fluid mechanics. The brand promise—"Keep Flowing, Keep Warming"—guides Cokaren's development of water system accessories that improve domestic comfort, thermal efficiency, and environmental safety.
Cokaren focuses on smart hydronic balancing, high-efficiency mixing stations, and architectural integration. By combining modern aesthetics with technical functionality, Cokaren supports Yongda's growth as a major supplier of residential climate control technology.
Yongda's corporate operations are structured around four primary values: Struggle, Enterprising, Pragmatic, and Innovative. With a customer-centric and quality-focused mission, the company implements a strict quality policy summarized as: "Fine work, no leakage."
Yongda maintains systematic management frameworks certified to global standards:
• ISO9001:2015 Quality Management Systems
• ISO14001:2015 Environmental Management Systems
• ISO45001:2018 Occupational Health and Safety Systems
These certifications ensure that manufacturing processes, working conditions, and product performance comply with international industrial safety and quality requirements.
Global procurement teams must comply with regional environmental and mechanical standards, including CE marks for Europe and NSF/ANSI lead-free specifications for North American potable water systems. Yongda ensures all materials meet these requirements, easing the compliance burden for importing partners.
Yongda maintains full metallurgical traceability, performing spectral analysis on incoming copper alloys. This ensures that every brass valve, fitting, or manifold meets specific tensile strength, dezincification resistance, and chemical composition standards.
With an 80,000 square meter facility and over 600 pieces of equipment, Yongda supports high-volume manufacturing while maintaining stable lead times. This scale helps global distributors minimize stockouts and manage inventory fluctuations.
Efficient hydronic management requires precise system design. Yongda designs and manufactures comprehensive fluid distribution systems that integrate filtration, pressure management, dynamic mixing, and zonal distribution. These components help maintain thermal efficiency and reduce energy consumption in residential and commercial buildings.
System integration illustrating filtration, thermal regulation, and flow distribution pathways.
The first line of defense in domestic water sanitation, filtering up to 98% of particulate impurities.

Technical Details >To support transition toward high-efficiency building designs, Yongda is focusing on three key areas in its product roadmap:
1. Smart Integration: We are incorporating digital actuators and sensors into our brass manifolds and valves. This enables real-time monitoring of flow rates and temperatures, allowing systems to integrate with smart building management platforms.
2. Advanced Lead-Free Alloys: In response to tightening global lead limits in drinking water regulations, Yongda is expanding the use of bismuth-based and silicon-based lead-free brass alloys, ensuring compliance with future environmental standards.
3. Advanced Automation: We are updating our Yuhuan factory with automated machining and testing systems. These upgrades improve manufacturing tolerances, lower product rejection rates, and increase output capacity.
Integrates isolation and filtration into a single body, saving space and reducing installation points in plumbing setups.
Provides manual and automatic adjustment of thermal inputs to maintain target room temperatures.
