Engineered to withstand rigorous system demands, complying fully with European CE directives and Belgrade district heating parameters.
Serbia's rapid industrialization, particularly in major cities such as Belgrade, Novi Sad, and Niš, has fueled massive growth in the residential and commercial construction sectors. Government investments in district heating infrastructure, along with initiatives to improve thermal efficiency in historic and new public structures, have created strict requirements for robust, low-maintenance flow control solutions.
As the country aligns with EU environmental protocols and adapts to energy efficiency laws (under the Energy Community Treaty framework), the demand for high-performance HVAC systems has skyrocketed. Designers and plumbing contractors are moving away from cast iron and low-grade polymers, prioritizing CW617N and CW614N dezincification-resistant brass alloys to protect system integrity from severe winter fluctuations.
Our solutions focus on providing thermal stability, low-pressure drops, and precise hydronic balancing. This ensures district heating substations and residential underfloor distributions perform optimally, offering long service lives with zero down-time.
A comprehensive overview of our engineered systems designed for complete domestic sanitation and radiant heating management.
The first line of defense in domestic water sanitation, designed to filter out 98% of particulates and impurities in the incoming pipe system.
Engineered with a robust spherical spool, ensuring efficient inflow and outflow control for hot and cold water cycles in domestic boilers.
Continuously purges trapped air pockets in heat pumps and water systems to prevent airlock issues and maintain consistent loop pressure.
Stabilizes target temperatures by mixing cold and hot return lines, protecting underfloor piping systems from excessive thermal stress.
A central control link that connects multi-zone actuators to maintain precise indoor environments and maximize energy efficiency.
Filters particulate matter, manages air discharge, controls flow pathways, and monitors temperature/pressure changes directly at the manifold.
Founded in 1996, Yuhuan Yongda (formerly Yuhuan Yongda Plumbing Co., Ltd.) is located in Yuhuan, Zhejiang—the recognized "China Valve Capital." Over nearly three decades, our company has evolved into a premier developer and manufacturer of high-end brass valves, fitting assemblies, and custom HVAC components.
We position our products at the mid-to-high-end tier, focusing on eco-friendly materials and lead-free compliance. Our brand Cokaren carries the promise of "keep flowing, keep warming," ensuring modern water and heating infrastructure delivers reliable comfort to projects worldwide.
For Serbian mechanical contractors and import partners, regulatory safety compliance is critical. We operate under three major internationally certified frameworks:
Every valve production batch undergoes rigorous pressure testing. Under our strict policy of "Fine work, no leakage," we ensure zero drops in pressurized heating circuits, minimizing project liability for local distributors and mechanical teams.
Sourcing HVAC manifolds and valves from Yuhuan Yongda balances cost efficiency with high manufacturing standards. Our 45,000-square-meter facility houses custom forging machines, specialized multi-axis CNC lathes, and automated pressure testing rigs. This infrastructure keeps output high while maintaining tight dimensional tolerances.
Following the establishment of the China-Serbia Free Trade Agreement (FTA), importing high-quality brass components has become more straightforward. Reduced tariff rates, simplified customs processes, and direct freight paths through major European shipping hubs mean lower total cost of ownership (TCO) for local engineering teams.
Additionally, our logistics department provides comprehensive support for import clearances. We supply CE declarations of conformity, chemical composition certificates, and detailed bill of materials data sheets to streamline incoming customs clearance at ports like Rijeka and Bar.
Precision-engineered brass components and hydronic distribution accessories tailored for the Serbia commercial heating market.
New projects along the Sava River, such as Belgrade Waterfront, require advanced energy performance. The integration of centralized air-source heat pumps alongside complex underfloor radiant heating networks demands precise balance and temperature control.
Modern system designs focus on mitigating two common issues: scaling from mineralized mains water and flow imbalances between zones of varying distances. This has led to the widespread adoption of Y5020 Mixing Shunts and high-performance manifolds with integrated bypass assemblies. By stabilizing system pressures, these units help lower energy consumption and prolong boiler lifespans.
Additionally, introducing manual air venting plugs and pressure relief assemblies helps manage system bubbles, which can cause oxidation and cavitation inside municipal lines.
The global trend toward green building certifications (such as LEED and BREEAM) is directly influencing Serbian engineering standards. Sustainable designs require smart, responsive hydronic control systems rather than static manual ones.
Integrating thermo-electric actuators with zone thermostats allows for demand-driven flow allocation, preventing energy waste in unoccupied building areas. Furthermore, standardizing on low-lead and lead-free DZR brass alloys helps prevent heavy metal leaching, ensuring compliance with future clean drinking water regulations in Europe.
