Explore our flagship brass fluid control hardware designed for European boiler architectures, gas systems, and district heating terminals across Portugal.
As Portugal accelerates its energy transition under the National Energy and Climate Plan (PNEC 2030), the country's building services and HVAC sectors are undergoing a massive technological shift. The demand for highly efficient condensing boilers, solar thermal domestic hot water systems, and biomass installations has spiked in metropolitan hubs like Lisbon, Porto, and Coimbra. Central to these systems is the Boiler Angel Valve (commonly known as the high-flow angle isolation valve), which governs the incoming cold water and outgoing hot water supply loops.
"In compliance with European Standard EN 12164/EN 12165 for CW617N brass components, modern Portuguese plumbing architectures require high-performance angle valves that can prevent calcification and dezincification. With Portugal’s diverse municipal water parameters—ranging from the soft water of northern Porto to the highly mineralized hard water of the Algarve region—the metallurgical integrity of boiler control valves is paramount."
From an operational standpoint, Portuguese engineering contractors and district heating developers prioritize valves featuring spherical spools and double O-ring sealing systems. These mechanisms guarantee minimal pressure drop coefficients (Kv value) and a zero-leakage threshold under variable operating pressures. Furthermore, with the rising popularity of hybrid heat pumps integrated with gas boiler systems in Portugal, local suppliers require versatile OEMs capable of delivering customized BSP/NPT threads, temperature sensors, and filter-integrated configurations.

Yuhuan Yongda Fluid Control Co., Ltd. (known globally via our dynamic premium brand, Cokaren) operates on a simple quality directive: "Fine work, no leakage." Backed by decades of refinement in Yuhuan, the plumbing valve capital of China, our operations integrate state-of-the-art multi-axis CNC machines and automated optical inspection systems to guarantee zero defects. We leverage European standard CW617N forged brass as our primary substrate to guarantee durability and compliance with strict EU drinking water regulations.
To ensure that exporters and wholesalers in Portugal receive only the highest-grade products, we strictly test our alloys and mechanical configurations. Below are the design specifications adhered to by our engineering lines for the Portuguese and European markets:
| Technical Parameters | Standard Specifications | Applications in Portugal |
|---|---|---|
| Material Composition | CW617N, CW614N Brass (EN 12164 / EN 12165) | Low-lead, dezincification-resistant drinking water networks |
| Nominal Pressure | PN16 to PN25 (232 to 362 PSI) | Residential high-rise buildings & boiler feed loops |
| Operating Temperature | -20°C to 120°C | Condensing boilers, solar thermal systems & district heating |
| Thread Connections | ISO 228-1 Standard Parallel (G Thread) / NPT | Seamless coupling to European manifolds and gas boilers |
| Sealing Gaskets | PTFE Seat with Double EPDM O-Rings | Preventing thermal aging and system micro-leaks |
Our production protocols are verified under international standards, ensuring seamless importation and certification processes for Portuguese contractors:
The applications for our specialized boiler angel valves and distribution systems cover both residential and industrial energy sectors:
Widely utilized across southern Portugal (Algarve and Alentejo) where solar water heaters are legally mandated for residential installations. Our angle valves manage cold water intake and heat-exchanger loops without high-temperature degradation.
Our high-flow ball valves and mixing shunts are integrated into centralized hydronic heating infrastructures in Northern Portugal, ensuring efficient heat energy distribution and precise zone temperature management.
Combined with our premium brass manifolds and electric actuators, these valves form the backbone of modern residential heating designs in Lisbon, promoting energy savings and high indoor thermal comfort.
Yuhuan Yongda Fluid Control Co., Ltd. possesses a state-of-the-art manufacturing campus spanning over 45,000 square meters. Our production capability is calibrated for heavy OEM and ODM production lines, ensuring high capacity, fast lead times, and reliable delivery to global ports, including Lisbon and Sines in Portugal.
Our facility houses 80+ specialty CNC machining centers and digital optical spectrometers, which perform structural and material tests on every batch of raw brass rod. This rigorous procedure guarantees that the copper, lead, and zinc ratios strictly comply with DIN 50930-6 guidelines.
Additionally, we conduct 100% pneumatic testing under water on all valve shells and seats, identifying micro-porosities before products enter the packaging phase. That is why our Cokaren brand promise remains: "Keep flowing, keep warming."
Explore our main selection of brass radiator fittings, thermostatic controls, and compression units engineered for the Portuguese construction sector.
Looking ahead, the European Union's directive on decarbonized gas grids is driving major changes in Portugal's national energy sector (EN-H2 Strategy). Key projects, such as the Sines Hydrogen Valley, will introduce hydrogen blends into natural gas lines. This shift requires valve components that can handle small hydrogen molecules and prevent gas leakage. Our research and development center is actively engineering next-generation brass alloy formulations designed to withstand hydrogen embrittlement.
Simultaneously, the demand for high-efficiency buildings in Portugal requires valves that support smart technology. Cokaren is developing smart thermostatic radiator valves (TRVs) and mixing systems that connect with home energy management platforms via Zigbee and LoRaWAN protocols. Integrating IoT connectivity with forged brass helps technicians control flow dynamics in real time, reducing household emissions by up to 18%.

For the Portuguese market, we primarily manufacture our valves using European standard CW617N brass. This alloy is widely approved across the European Union for sanitary and drinking water systems, containing controlled lead levels to prevent toxic leaching.
Our standard production lead time is 30 to 45 days upon deposit confirmation. Shipping from our facility in Yuhuan to major Portuguese sea hubs (Lisbon, Leixões, Sines) takes approximately 30 to 35 days, depending on shipping lines and route availability.
We operate under a strict "no leakage" quality policy. Every single valve undergoes individual low-pressure and high-pressure pneumatic tests under water before assembly. This process ensures that no porous castings or assembly errors exit our production line.
Yes. We offer complete OEM and ODM customization services. This includes engraving your brand logo on the valve body, custom handle colors (red, yellow, blue), custom instruction manuals in Portuguese, and branded master cartons to support your domestic marketing presence.
Yes, our brass valves, manifolds, and electric thermal actuators are designed in compliance with the EPBD (Energy Performance of Buildings Directive) requirements, facilitating seamless integration with smart thermostats to achieve optimal energy efficiency classes.
