Premium brass valves, PE/PEX fittings, and high-performance HVAC components manufactured under strict ISO guidelines.
In modern commercial, municipal, and residential fluid systems, the integration of premium pressure reducing valves (PRVs) is vital to safeguarding downstream infrastructure. Unregulated pressure fluctuations lead to pipe ruptures, rapid component wear, boiler malfunction, and significant water waste. Partnering with a dedicated OEM pressure reducing factory is the definitive pathway for engineering firms and global distributors to obtain custom-configured, highly durable flow control solutions.
As a global leader in fluid mechanics manufacturing, we optimize our product development through precision forging, advanced metallurgy, and strict compliance with global hydraulic standards. Our goal is simple: deliver zero-leakage, energy-efficient pressure control valves designed to maintain system equilibrium under dynamic flow demands.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly known as Yuhuan Yongda Plumbing Co., Ltd.) was established in 1996 in the renowned "China Valve Capital" – Yuhuan, Zhejiang Province. Over the last quarter-century, the company has grown into a premier, highly dynamic plumbing valve enterprise integrating product design, research and development, custom production, and international sales.
Our expansive product portfolio is categorized into three major domains: high-grade brass valves, precision plumbing fittings, and advanced HVAC control products. The brand places a heavy strategic emphasis on middle to high-end market segments, prioritizing environmental protection, material safety, and mechanical longevity. This focus has made our catalog highly favored among building developers and distributors across North America, Europe, and Asia.
Operating from a state-of-the-art production base spanning over 45,000 square meters (with an actual usable area exceeding 80,000 square meters), our plant hosts more than 600 sets of advanced production and testing equipment. Among these are over 80 sets of specialized high-precision machine tools, allowing us to perform highly intricate OEM/ODM specifications for a diverse clientele in over 20 countries.
Our premium brand, Cokaren, represents our commitment to developing refined plumbing products with superior cosmetic appeal and unmatched mechanical performance. Cokaren's core promise, "Keep flowing, keep warming," translates our dedication to creating comfortable, reliable water delivery and indoor heating systems for families worldwide.
Our actions are guided by our core values: Struggle, Enterprising, Pragmatic, and Innovative. With a customer-centric and quality-focused approach, we adhere strictly to our motto: "Fine work, no leakage." Every production batch undergoes pressure testing to eliminate any trace of system leaks before dispatch.
To ensure complete safety and trust in global procurement channels, Yuhuan Yongda Fluid Control has established a robust management infrastructure:
Why the Yuhuan industrial cluster offers unparalleled technical and logistical advantages for international valve buyers.
Yuhuan, Zhejiang, is recognized globally as "China's Valve Capital." The localization of raw material suppliers, forging plants, surface treatment specialists, and logistical networks reduces transit overheads and lead times. This structural synergy allows us to produce high-end OEM pressure reducing valves with optimal cost-to-performance ratios.
Our factory features over 80 custom machine tools designed for highly precise tolerances. When manufacturing pressure reducing components, variations of even a fraction of a millimeter can alter spring tension and piston sealing, leading to pressure drift. Our strict tolerances maintain reliable outlet pressures under varying input fluctuations.
International regulations like NSF/ANSI 61 and the European Drinking Water Directive require trace-level lead content in potable water applications. Our hot forging department utilizes specialized lead-free and dezincification-resistant (DZR) brass alloys to prevent chemical leaching and structural degradation over decades of use.

The first line of defense in domestic water sanitation, filtering up to 98% of particulates and suspended solids in the pipeline.
Used to control the inflow and outflow of cold water and hot water in the boiler, with Spherical spool.
Used to discharge excess air in the air source water heater to ensure stable operation of the equipment.
Used to mix cold and hot water in pipes, stabilizing temperature, protect pipeline.
Industrial and commercial sourcing of pressure control solutions requires matching strict mechanical and regulatory specifications. When procurement departments select an OEM pressure reducing valve factory, they prioritize compliance, precision, and reliable lead times:
The fluid control industry is shifting toward smart, automated architectures. With the rise of IoT and intelligent building control systems, static pressure regulators are transforming into dynamic control devices. Integrated electronic actuators receive signals from downstream pressure sensors, adjusting flow rates to maintain set parameters.
Additionally, sustainability is driving production changes. Eco-friendly manufacturing practices that reduce heavy-metal waste and lower the carbon footprint of foundry operations are becoming mandatory qualifications for European and American institutional buyers.

Critical engineering and purchasing answers regarding pressure reducing valves and global sourcing protocols.
A: A pressure reducing valve (PRV) automatically reduces high fluctuating inlet water pressure to a stable, lower downstream pressure. This protects pipe networks, limits flow velocities, reduces noise, and prevents damage to fixtures, boilers, and appliances.
A: As "China's Valve Capital," Yuhuan offers a complete industrial ecosystem that optimizes lead times and component sourcing. Factories leverage regional forging, CNC tooling, and material suppliers, reducing transportation overheads and maintaining cost-effective production.
A: We use certified low-lead and lead-free brass alloys, such as CW617N and DZR brass, that comply with NSF/ANSI 61 and European drinking water safety directives. These alloys are monitored using spectrometer verification to prevent lead contamination.
A: Yes. As an OEM manufacturer, we calibrate target pressure ranges to buyer specifications (e.g., preset downstream at 3 bar, adjustable from 1.5 to 6 bar) before shipment. Each valve undergoes factory pressure testing to verify accuracy.
A: Our export products hold CE marking, indicating compliance with European safety, health, and environmental standards. We also align production processes with ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 guidelines.
A: Automatic air vents discharge accumulated air pockets from radiators and floor manifolds. Removing air prevents air locks, reduces noise, minimizes oxidization corrosion, and maintains system thermal transfer efficiency.
A: Lead times vary based on custom tooling and volume, but standard manufacturing runs range from 30 to 45 days. This includes material casting or forging, high-precision machining, pressure testing, and custom brand packaging.
A: We utilize multi-stage quality control. This includes checking raw material composition, monitoring dimensional tolerance during CNC machining, and executing air and water pressure testing on every completed valve to ensure a zero-leak rate.
