High-performance motorized and manual valves engineered to meet EU energy directives and industrial standards.
Slovakia has emerged as one of Central Europe's most dynamic automotive and manufacturing powerhouses. With cities like Bratislava, Nitra, and Žilina hosting large-scale assembly hubs (Volkswagen, Jaguar Land Rover, Kia, and Stellantis), there is an urgent structural need for advanced thermal control systems. The modernization of district heating schemes, combined with EU energy efficiency targets, requires localized integration of motorized valve actuators and intelligent flow regulators.
Additionally, Slovakia's transition away from traditional fossil fuel dependence to district heating, residential biomass setups, and solar thermal loops necessitates high-precision brass components. Sub-freezing winter climates require durable heating systems that prevent fluid stagnation, regulate multi-zone underfloor manifolds, and stabilize system pressure dynamically.
Globally, the building services sector is moving rapidly toward automation. Hydronic integration, smart balancing, and motorized control valves represent the baseline architecture of zero-carbon infrastructure. The global motorized valves market is shifting toward highly integrated IoT actuators capable of communicating via Modbus, BACnet, or wireless protocols directly with Building Management Systems (BMS).
Procurement directors globally are facing pressure to source valves that balance metallurgical purity (complying with low-lead and dezinification resistance regulations like EN 12165) with competitive total cost of ownership. The ability to supply robust actuators with IP67 enclosure ratings, high shut-off differential pressures, and low power consumption has become the benchmark for international suppliers.
The manufacturing hub of Yuhuan, China, representing the "Valve Capital of China", provides a massive supply advantage. Over decades, local industrial clusters have optimized brass forging, precision machining, and automatic electronic actuator testing. Chinese factories like Yuhuan Yongda feature integrated production lines that control everything from raw bar casting and forging to final pneumatic testing.
By coupling advanced manufacturing with robust material supply networks, Chinese manufacturers achieve unparalleled efficiency. Short cycle times, consistent metallurgical purity, and strict quality control systems allow Slovakian distributors and OEMs to procure high-end components at competitive pricing, ensuring strong margins and rapid deployment cycles in commercial and residential HVAC projects.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was founded in 1996. Headquartered in Yuhuan, Zhejiang, the heart of China's plumbing industry, we are a professional enterprise specializing in the design, development, production, and sales of high-performance plumbing valves, fittings, and HVAC systems.
Our comprehensive portfolio is structured around three core pillars: brass valves, plumbing fittings, and specialized HVAC products. Strategically positioned for middle and high-grade global markets, our products prioritize environmental compatibility, metallurgical purity, and energy efficiency. They are widely utilized by contractors and distributors across North America, Europe, and dynamic Central European markets like Slovakia.
With a factory area exceeding 45,000 square meters (usable area reaching 80,000 square meters) and over 600 sets of advanced manufacturing and testing devices (including 80 dedicated machine tools), we offer robust production capabilities and custom design adjustments. Our premium brand, Cokaren, represents our commitment to refined product aesthetics and strict quality control under the brand promise: "Keep flowing, keep warming".

Intelligent multi-room thermal regulation.
Filters debris and controls manifold zone balancing.
Modern commercial buildings in central Europe require dynamic hydronic balancing. Traditional static balancing valves are often insufficient for systems with variable speed pumps. Our motorized flow control valves feature precision gearboxes and high-torque motors, providing reliable shut-off even under elevated differential pressures. The integration of high-performance elastomers and custom brass alloys limits internal friction, extending actuator service life and reducing maintenance requirements.
For chemical stability and long-term durability, our valves use forged brass resistant to dezincification (DZR). This is particularly critical in regions with high water hardness or aggressive chemical treatments. Through strict ISO 9001:2015 manufacturing workflows, each valve body is pressure-tested before assembly, ensuring zero defects and leak-free performance in high-pressure applications.
To successfully supply HVAC and heating products to the European and North American markets, strict regulatory compliance is essential. Our manufacturing facilities are certified to international management standards, including ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health & Safety).
Our brass valves and fittings are manufactured to comply with strict European CE guidelines and RoHS environmental restrictions. We use lead-free brass formulations that meet strict drinking water regulations. Our manifolds, motorized mixing systems, and zone control valves are designed for straightforward integration into European hydronic systems, matching DIN and EN thread specifications for trouble-free installation on-site.
A complete selection of compression fittings, distribution manifolds, and radiator control systems.
In addition to our primary motorized selections, we offer a comprehensive catalog of forged brass accessories, manual isolation valves, and pipe connector adapters for municipal and residential heating projects.
Essential insights on compliance, design specifications, and logistics for European distributors and contractors.
Yes, all of our electronic actuator units and motorized valves carry CE certification and comply with the Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) requirements. Additionally, our brass manufacturing processes meet ISO 9001 and ISO 14001 criteria, and our brass materials align with EN 12164/12165 requirements for industrial plumbing installations in European Union territories, including Slovakia.
We work with standard CW617N, CW614N, and low-lead CW602N (Dezincification Resistant - DZR) brass alloys, depending on project specifications. For drinking water applications in Central Europe, we supply lead-free brass formulations to ensure full compliance with EU public health directives and local Slovak water quality regulations.
Our quality policy is based on "Fine work, no leakage." Every forged valve body undergoes automated dimensional inspection and 100% pneumatic pressure testing to detect micro-fractures or structural defects before assembly. Completed assemblies, including manifolds and motorized valves, undergo functional checks, torque profiling, and leak testing before shipment.
Yes. As a dedicated OEM/ODM manufacturer, we can configure electric actuators to match specific project requirements. We offer support for 230V AC, 24V AC/DC, and 12V DC systems, with control options including 2-point, 3-point, or modulating (0-10V / 4-20mA) inputs. Running times, cable lengths, and connector designs can also be customized to fit your system design.
Standard production lead times range from 30 to 45 days after deposit confirmation, depending on the order size and custom specifications. We offer shipping through major Chinese ports, such as Ningbo or Shanghai, with transit routes to Slovakia via rail networks or marine freight to European entry ports like Koper, Hamburg, or Rotterdam, followed by overland delivery to Bratislava, Košice, or other regional hubs.
Yes. Our motorized valve systems and smart LCD thermostats (such as the Y9031 series) can be designed to interface with modern Home Automation and Building Management Systems (BMS) through dry contact relays, Wi-Fi protocols, or RS485 Modbus. This enables integration into energy management architectures to optimize smart HVAC operations in real time.
