Explore our premium selection of highly durable, precision-engineered brass valves tailored specifically for Barcelona’s residential plumbing networks, commercial hydronic systems, and water engineering standards.
Barcelona and the wider Catalonia region operate under highly demanding municipal directives regarding environmental conservation, water saving, and carbon footprint reduction (CTE Code - Código Técnico de la Edificación). Large commercial infrastructure developments, multi-family housing projects, and public utilities are upgrading their plumbing networks to support high-efficiency thermal loops, hydronic zoning systems, and lead-free configurations.
Industrial operations situated along the Llobregat and Besòs river corridors require specialized valves that resist corrosion while maintaining steady flow profiles. High-quality brass forged valves with custom threads are crucial to satisfying Barcelona's strict pressure-tight regulations and ensuring sustainable operation in coastal, saline-rich maritime environments.
The urban transformation of Barcelona (such as the 22@ Innovation District) has spurred demand for localized energy distribution networks. Underfloor radiant heating networks, district cooling systems (such as Districlima in Forum & Poblenou), and heat pump configurations require rigorous balance and flow isolation solutions. Premium manifold integrations, thermostatic actuators, and bypass groups must deliver seamless performance under peak thermal loads.
Our engineering division designs valves and brass components specifically mapped to the operating parameters of modern Spanish building management systems, ensuring seamless integration and high durability.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was founded in 1996 in the world-renowned "China Valve Capital" – Yuhuan, Zhejiang. We are a specialized, vertically integrated valve enterprise focusing on the continuous research, engineering design, development, high-volume production, and international sales of premium HVAC and plumbing hardware.
Our catalog is strategically cataloged into three core lines: environmental brass valves, custom plumbing fittings, and advanced HVAC control products. Positioned globally in the medium-to-high tier market, our product developments prioritize lead-free safety, environmental protection, and compliance with severe Western European and North American plumbing certifications.
Supported by a state-of-the-art facility covering 45,000 square meters (with an actual usable production and logistical floor area of over 80,000 square meters), our plant deploys over 600 units of advanced manufacturing tools. This includes 80+ specialized multi-axis CNC machines and automated testing equipment capable of performing 100% pneumatic-hydraulic leak tests, ensuring that every batch shipped to Spain meets the strict European threshold of zero leakage.
Cokaren, our premium brand identity, is dedicated to delivering highly refined industrial aesthetics, zero-defect quality, and complete engineering services to our European distribution partners.
"Keep Flowing, Keep Warming"
Cokaren represents our commitment to modern, low-carbon building systems, providing highly reliable hydronic and control accessories to residential and industrial spaces across Barcelona and Southern Europe.
"Fine work, no leakage."
As Barcelona pushes forward with smart city technologies and high-efficiency building mandates, Yuhuan Yongda continues to invest in next-generation material research and flow intelligence.
Accelerating the transition to CW617N, CW602N (DZR), and lead-free formulations (under 0.25% Pb) to conform to the most stringent EU drinking water guidelines (EDW). Our metallurgy laboratory performs continuous optical emission spectrometry to verify elemental purity before forging.
Integrating ultra-low power consumption thermoelectric actuators with smart building management systems (BMS). Our upcoming range features self-balancing dynamic balancing valves (PICV) that communicate with local HVAC controllers via Modbus/BACnet protocols.
Developing accurate Revit/BIM models for all manifolds and ball valve products, allowing Barcelona design bureaus and construction engineers to run pre-construction hydraulic and pressure drop simulations inside digital layouts.
Comprehensive, interconnected hydronic control groups optimized for eco-conscious residential and commercial buildings throughout Catalonia.
The first line of defense in domestic water sanitation, filtering 98% of particulate impurities and sediment to protect sensitive terminal valves.
Optimized spherical spools designed to regulate inlet and outlet cold/hot loops under cyclic pressure profiles.
Automatically expels air pockets from heat pump loops, eliminating cavitation risks and protecting system thermal efficiency.
Blends cold and hot fluid streams with thermostatic accuracy, preventing thermal shock and protecting hydronic tubing.
Senses room temperature variations to control thermostatic manifold actuators for maximum thermal comfort.
High-capacity isolation and balancing valves featuring integrated instrumentation ports for pressure and temperature measurements.
Yuhuan Yongda operates on the forefront of China's automated manufacturing revolution. Our manufacturing cluster integrates raw material extrusion, continuous hot forging, precise multi-axis CNC finishing, automated chrome/nickel surface plating, and fully integrated automated assembly loops. This deep internal supply chain prevents third-party delays and guarantees uniform material quality.
Our quality management workflow conforms strictly to international frameworks, assuring our Spanish and broader European partners of complete supply chain reliability, health-safety metrics, and environmental responsibility.
We supply products tailored to meet local plumbing practices in Spain. The thread connections match BSP ISO 228-1 specifications, which are standard in Barcelona. Our nickel-plated and chrome finishes pass intensive salt-spray corrosion tests to withstand typical coastal air salinity in Catalonia.

Ensure the brass alloy specification aligns with European standards. In Spain, CW617N brass (containing 58-60% copper, 1.6-2.5% lead, and the rest zinc) is widely specified for general plumbing. For drinking water applications, ensure lead-free alternatives are selected to meet sanitary regulations.
Industrial operations in Catalonia often require PN16 or PN25 pressure-rated brass valves. Make sure to specify the peak thermal conditions of the media, especially for solar thermal systems, where EPDM or PTFE seals must withstand temperatures exceeding 120°C.
Always specify the correct thread standards. For Barcelona and wider EU networks, BSPP (parallel) or BSPT (tapered) threads conforming to ISO 228-1 are mandatory for clean plumbing and pipe fitting linkages. For export projects, NPT connections can be custom manufactured.
For valves installed in coastal locations or exposed environments, specify high-quality nickel plating or polished chrome finishes. This step prevents oxidation, maintains long-term appearance, and ensures easy valve operation over years of service.
Clear, detailed answers regarding technical parameters, compliance certifications, shipping logistics, and customization options for Barcelona and Spain.
Our standard products are manufactured using CW617N brass, the predominant material grade for European plumbing networks under EN 12165. For specific drinking water projects in Spain, we supply DZR brass (CW602N) or lead-free formulations to comply with the European Drinking Water Directive.
Yes, all our stainless steel and brass underfloor water heating manifolds, thermostatic assemblies, and motorized controls are fully CE certified. We provide complete Declarations of Conformity (DoC) and test reports to support project inspections in Spain.
Standard production cycles are 30 to 45 days, depending on batch sizes and customization requirements. Sea shipping from Shanghai or Ningbo Port directly to the Port of Barcelona takes approximately 25 to 30 days. For urgent construction needs, we can arrange air cargo shipment.
