Engineered specifically to survive demanding high-pressure hydronic configurations in Middle Eastern developments.
The UAE HVAC market stands at a critical technological intersection. Characterized by rapid urbanization, iconic high-rise architectures, and hyper-arid climates where summer temperatures exceed 50°C, the demand for high-efficiency climate regulation is unprecedented. In this environment, heating, ventilation, and air conditioning (HVAC) systems are not luxuries—they are core life-support and comfort mechanisms that consume over 70% of building energy output.
Under Abu Dhabi's Vision 2030 and Dubai's Al Sa'fat Green Building System, HVAC valve compliance relies heavily on reducing thermal stress, optimizing water flow velocity, and preventing mechanical leakage. Modern installations demand integration with District Cooling networks (such as those managed by Empower and Tabreed) requiring highly specialized pressure-independent control valves (PICVs) and heavy-duty brass alloy valves capable of resisting high levels of dezincification (DZR).
Yuhuan Yongda Fluid Control Co., Ltd. delivers high-specification engineering components designed to withstand severe thermal expansion, extreme system pressures, and localized sand and salt-laden air. By utilizing advanced forging techniques, we guarantee absolute reliability and operational longevity for high-density commercial developments and industrial complexes alike.
Aligning international standards with Middle Eastern mechanical, electrical, and plumbing (MEP) designs.
Traditional HVAC setups fall short when managing the massive fluid volumes present in UAE's district cooling systems. Our dynamic balancing and differential pressure control systems eliminate the "Low Delta-T Syndrome" that plagues chillers, ensuring high performance under maximum ambient load.
Humidity and high salinity in coastal regions like Dubai Marina and Abu Dhabi Corniche pose severe corrosion challenges. Yongda utilizes premium lead-free and dezincification-resistant (DZR) brass alloys, ensuring the integrity of connections and extending system lifespan.
Our motorized valves and smart thermostats interface seamlessly with centralized Building Management Systems (BMS). Using precise modulating controls, we help buildings achieve high LEED certifications and Estidama Pearl ratings through real-time energy conservation.
Founded in 1996 and nestled in Yuhuan, Zhejiang—known as the "China Valve Capital"—Yongda has evolved from a local manufacturer into a globally recognized fluid control partner. Spanning a vast 45,000 square meters factory footprint (with 80,000 square meters of actual usable area), we operate over 600 sets of advanced testing and production machines, serving projects in over 20 countries.
Under our premium brand, Cokaren, we deliver "keep flowing, keep warming" assurance. We strictly adhere to our quality policy: "Fine work, no leakage." Every valve undergoes pressure tests, material composition inspections, and cycle lifetime evaluations, meeting stringent Middle Eastern structural requirements.
Our processes are fully certified to international standards, including ISO9001:2015 (Quality Management), ISO14001:2015 (Environmental Management), and ISO45001:2018 (Occupational Health & Safety).

Understanding the engineering decisions that make Yongda and Cokaren products standard in high-ambient operations.
Operating HVAC valves in the GCC region, particularly in coastal UAE cities like Abu Dhabi, Dubai, and Ras Al Khaimah, introduces unique chemical and mechanical challenges. Ground temperatures, soil salinity, and high humidity accelerate galvanic corrosion in low-quality metallic alloys, while high-velocity chilled water systems can quickly erode internal components.
In hot, humid climates with high-mineral water content, standard brass can suffer from dezincification—a process where zinc selectively leaches out of the alloy, leaving a porous, mechanically weak copper structure prone to catastrophic leakage. Yongda utilizes CW602N and custom DZR brass formulations. These materials are treated with inhibitors like arsenic to stabilize the alloy, ensuring structural integrity even in harsh operating conditions.
Supertall skyscrapers in Dubai demand high pressure ratings. Standard valves fail under the high static heads required to pump chilled water to top floors. Our commercial-grade valves are rated for PN25 and PN40 operations. Combined with high-grade EPDM gaskets and PTFE seals, our systems handle massive temperature differentials (+5°C chilled water up to +80°C hot water loops) without degradation.
Modern Variable Air Volume (VAV) and Fan Coil Unit (FCU) systems demand linear flow characteristics. Our motorized control valves use precisely engineered parabolic plugs, allowing BMS systems to modulate flow rate based on real-time load requirements, eliminating wasteful over-pumping.
