Explore our top-tier brass valves and system components engineered for precision distribution networks.
Industrial procurement departments globally require high-reliability brass ball valves and manifolds to sustain pressure and thermal stability. Whether setting up smart heating infrastructure in Northern Europe or managing residential water grids in North America, sourcing partners seek the ideal equilibrium between manufacturing precision and factory direct pricing structures.
Yuhuan Yongda Fluid Control Co., Ltd. resolves these market requirements through advanced tooling, automated forging lines, and standardized chemical treatments. By leveraging over two decades of localized engineering expertise in Yuhuan—widely recognized as the "China Valve Capital"—we manufacture high-pressure valves, custom manifolds, and durable fittings that comply with severe European and American regulatory guidelines.
Selecting the proper valve involves understanding pressure parameters, material metallurgy, and corrosion resistance profile, ensuring total system efficiency and minimization of long-term maintenance overhead.
Analyzing key structural, material, and pressure performance parameters of brass ball and manifold valves.
Our hydronic and hydraulic control solutions are engineered to withstand continuous operating pressures and temperature cycles. Brass alloys, such as HPb57-3, CW617N, and DZR (Dezincification Resistant) lead-free brass are selected based on client specification to eliminate premature system failure.

Hot Forging Technology: Rather than using cast brass, which is prone to microscopic pinholes and structural impurities, Yongda utilizes hot forging presses. This consolidates the metal structure, ensuring high density and eliminating risk of structural leakages under high fluid pressure.
Precision CNC Machining: Threads are cut with tight tolerances conforming to ISO 228 (BSP) and ANSI/ASME B1.20.1 (NPT). This ensures consistent torque values during piping assembly and avoids joint strain.
Modern smart home and industrial systems demand highly coordinated, leak-free component integration.
Yongda manifolds, mixing shunts, and temperature-controlled water dividers form the central nerve center for modern radiant floor heating, balancing pressure drops across multi-loop circuits and ensuring homogeneous heat distribution.
Boiler Angle Valves (Y5001/Y5002) and automatic air vent valves protect heat exchangers against pressure spikes and entrained air lockups, guaranteeing proper heat-transfer fluid flow and preventing mechanical fatigue.
Integrating pre-filtration units like the Y9021 water filter with high-performance brass gate valves safeguards end-user tap outlets by stripping 98% of particulates, shielding downstream sanitary fittings.
Established in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has developed into a leading, technology-driven brass valve manufacturer based in the valve production hub of Zhejiang, China.
We target mid-to-high-grade international projects with our three core product families: brass valves, plumbing fittings, and HVAC distribution components. Through our export brand, Cokaren, we carry out our core principle: "keep flowing, keep warming," providing global households with durable, leak-free performance.
Our production facilities stretch across a footprint of 45,000 square meters, providing a highly optimized usable floor area of 80,000 square meters. Inside, we maintain dedicated spaces for automated forging, multi-axis CNC machining, surface finishing, and computer-assisted hydraulic quality checking.
Our quality pledge, "Fine work, no leakage," is embedded into our quality management systems. Yongda is certified under:
Every single valve undergoes hydrostatic and pneumatic pressure testing to guarantee absolute seals prior to packaging. Spectrometer analysis is performed on each batch of raw copper material to prevent lead or zinc leakage issues. By adhering to CE certification standards, we provide European distributors and global HVAC system contractors with complete regulatory safety.
Understanding variables that determine the cost-structure of industrial-grade brass valves.
When sourcing hydraulic and plumbing valves from China, price lists are not static but correspond closely with raw material indexes, exchange rates, and design customization. Yongda maintains pricing transparently, basing quotes on:
Purchasing managers can request updated, itemized pricing catalogs tailored to distinct pressure classes and dimensional specifications by contacting our export desk directly.
Answering major technical and logistical inquiries of international purchasing teams.
For standard catalog items, production is completed within 30 to 45 days. OEM and customized designs, including molding adjustments and sample approvals, take approximately 45 to 60 days depending on the volume and technical requirements.
We implement double-testing protocols. Every valve is subjected to high-pressure air testing and hydrostatic tests under working pressures. We reject casting methods, utilizing advanced hot forging to maintain metal density, and enforce ISO 9001:2015 quality processes across our assembly lines.
Yes, we export to over 20 countries. We offer CW617N brass and low-lead or lead-free alloys (such as C37700 or DZR brass) specifically engineered to meet EPA, NSF/ANSI 61, and European drinking water standards.
Yes, through our specialized brand Cokaren, as well as OEM services, we offer customized laser markings on valve bodies, bespoke retail packaging, and customized outer carton shipping boxes tailored to your brand identity.
Complete your HVAC and plumbing distribution assemblies with our field-tested components.
