As the Île-de-France region executes its ambitious carbon-neutrality master plan under the RE2020 (Réglementation Environnementale 2020) mandate, the commercial, residential, and industrial heating infrastructure of Paris is undergoing rapid technological modernization.
From the historic Haussmannian structures requiring delicate hydronic balance systems to the expansive modern HVAC systems of La Défense, top-tier water filtration and fluid control components are vital. Paris's municipal drinking water grid (managed by Eau de Paris) and the deep network of district heating operated by the Compagnie Parisienne de Chauffage Urbain (CPCU) dictate strict operating parameters. The demand is surging for robust brass strainers, backflow preventers, and mixing valves that are certified for sanitation and high thermo-mechanical stress.
For Paris mechanical contractors, wholesale distributors, and engineering firms, sourcing fluid control hardware that satisfies both strict French regulations (such as the Attestation de Conformité Sanitaire - ACS) and the economic requirements of high-volume projects is a critical operational dynamic.
High-performance valves and strainers optimized for the strict water treatment and industrial networks of the French market.
Engineered for urban pumping assemblies and district heating intake, offering low pressure drop and micro-particle suction filtration.

View Specifications →Exporting brass fluid components to the Paris region requires strict adherence to European sanitary protocols and local French building codes. The primary technical hurdle is obtaining the ACS (Attestation de Conformité Sanitaire) certification, a mandatory validation for any material coming into contact with water intended for human consumption.
To meet European standards, our valves use sanitary-grade CW617N, CW602N (DZR), and lead-free brass formulations that comply with the German Federal Environment Agency (UBA) positive list, keeping lead migration below 0.1% for domestic installations in France.
Our manufacturing operations integrate carbon footprint assessments. We support Paris project managers in completing PEP ecopassport® profiles, which are essential for building lifecycle analysis in new French construction developments.
From thread forms conforming to ISO 228-1 (G-threads) to specific pressure classifications (PN10, PN16, PN25), our products are customizable to meet the mechanical parameters of standard French heating and sanitary equipment.
Established in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved into a premier plumbing valve manufacturer, located in the "China Valve Capital" of Yuhuan, Zhejiang.
For over two decades, our engineering teams have specialized in the design, development, production, and distribution of high-grade brass valves, fittings, and HVAC distribution components. Under our premium brand Cokaren, which operates on the brand promise of "keep flowing, keep warming," we supply refined domestic and commercial water system accessories that offer durability and high thermal efficiency.
Our expansive manufacturing footprint reaches over 45,000 square meters, with an actual usable production floor area of 80,000 square meters. By deploying more than 600 sets of advanced manufacturing and testing devices (including 80+ sets of dedicated multi-axis CNC machine tools), we ensure that high-volume orders for European markets are delivered with zero-defect quality control.
Integrating clean-water pre-filtration and mechanical HVAC balancing for high-efficiency European systems.
Designed as the primary defense in sanitary plumbing networks. Filters out 98% of sediment and physical piping impurities.
Controls water circulation for boilers and heat exchangers, featuring a chrome-plated spherical spool design.
Automatically releases accumulated air pockets within hydronic loops, maintaining system pressure stability.
Maintains target temperatures in underfloor systems by blending hot water supply with return lines.
Monitors system operation, working in sync with manifolds and valves to maintain precise zone temperatures.
Combines particulate filtration, automatic air venting, and integrated temperature/pressure gauge ports.
Procurement directors in Europe face volatile raw material costs and strict shipping schedules. To manage these challenges, they rely on supply chains that balance scale, technological capability, and strict quality control.
As a specialized manufacturer based in Yuhuan, Yongda provides direct access to China's premier industrial brass cluster. This geographic location enables efficient sourcing of raw materials, automated forging services, and comprehensive surface treatment solutions.
How our specialized brass components are deployed within typical infrastructure contexts across Paris.
Vintage buildings feature high-volume hydronic systems with low design tolerances. Our temperature control valves and inline Y-strainers protect historic piping from scale and debris while providing modern thermal balancing.
High-rise buildings require high-capacity, durable equipment. Yongda's heavy-duty manifolds and high-pressure check valves are designed to withstand the hydrostatic pressure peaks common in multi-floor vertical heating loops.
Underfloor heating and district energy links are standard in new developments across Saint-Ouen and Saint-Denis. Our Smart Thermostats and Mixing Shunts integrate with these networks to optimize heating efficiency and meet RE2020 standards.
