High-performance valves and connection accessories engineered for strict safety standards and system integrity.
Providing critical stabilization in volatile multi-phase piping systems worldwide.
Within modern hydraulic infrastructure, pressure regulation stands as the primary technical challenge. High-pressure reducers (Pressure Reducing Valves - PRVs) act as the critical frontline barrier, protecting downstream manifolds, heat exchangers, and municipal water circuits from the catastrophic effects of sudden pressure spikes and cavitation erosion.
Whether navigating the complex dynamics of industrial district heating (HVAC) systems or regulating municipal domestic water supplies, a high-pressure reducer must demonstrate absolute reliability. At Yuhuan Yongda Fluid Control Co., Ltd., our ODM and OEM solutions are developed based on extensive simulation of fluid mechanics. We construct high-grade piston and diaphragm regulators that actively compensate for inlet fluctuations, guaranteeing a constant, controlled outlet pressure under varied dynamic loads.
Our ongoing development focus addresses key industry pain points: reducing turbulence-induced acoustic pollution, optimizing structural wall thickness to prevent fatigue cracking, and implementing anti-corrosion surface treatments to combat aggressive fluid chemistries.
Established in 1996 | Zhejiang Yuhuan - The Valve Capital of China
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has grown to become a leading plumbing valve enterprise. Operating in Yuhuan, Zhejiang, we manage a vertically integrated manufacturing campus dedicated to product design, development, production, and sales.
Our product portfolio is divided into three primary categories: brass valves, brass fittings, and HVAC products. Positioned in the mid-to-high-grade segment, our solutions are engineered for long-term environmental durability. They are widely utilized by municipal developers, system engineers, and distributors across North America, Europe, and Asia.
Under our premium brand, Cokaren, we deliver refined plumbing and heating solutions. Built around the brand promise "keep flowing, keep warming", Cokaren works to supply advanced hydronic control accessories that improve energy efficiency and comfort in residential and commercial properties globally.
Why sourcing from the heart of China's plumbing capital ensures unmatched scale and efficiency.
Yuhuan serves as the global industrial cluster for brass valve manufacturing. Our factory has immediate access to certified copper refineries, precision mold manufacturers, and surface-finishing specialists. This cluster allows us to maintain rapid raw material sourcing, lowering turnaround times for large-scale ODM orders.
Equipped with over 600 sets of production and testing machinery, including 80+ dedicated multi-axis CNC machine tools, our factory ensures sub-millimeter tolerances on valve internal galleries. This automated precision ensures high repeatability and reduces unit variance across production runs of 100,000+ units.
We perform 100% pneumatic testing for air tightness and high-pressure hydraulic tests to identify structural micro-voids. By enforcing a policy of "Fine work, no leakage", we verify that every high-pressure reducer leaving the factory floor meets its design ratings under load.
International procurement managers face complex regulatory, environmental, and material trace requirements. Our fluid control systems are engineered to help clients navigate these strict regulatory compliance landscapes.
Our facilities and operations are fully certified under the following international standards:
For custom ODM projects, we offer material test reports (MTRs) certifying chemical composition, tensile strength, and compliance with lead-free mandates (such as NSF/ANSI 61 and EN 12165). This documentation simplifies customs clearance and localized engineering audits.
An integrated look at our core HVAC, water purification, and thermodynamic balancing components.
An efficient hydronic heating and energy distribution system relies on precision coordination between several critical control points. From the primary filtration units protecting mechanical parts, to temperature-balancing manifolds, each component helps maintain pressure stability and minimize system heat loss.
The first line of defense in domestic water sanitation, filtering 98% of incoming solid impurities.
Features a spherical spool to control hot and cold fluid inputs at boiler inlets.
Designed to discharge air pockets in heat pump and water heating systems, preventing air locks.
Blends return hot and cold water streams to stabilize temperature and prevent thermal stress.
Integrates with manifold systems to enable zoned space-temperature adjustments.
Designed to capture pipeline particulate and support balanced system diagnostics.
Distributes flow to multiple heating zones, maintaining consistent hydraulic resistance.
Adapting fluid control components to meet regional technical standards and installation practices.
Underfloor heating systems across Northern and Central Europe require precise, lower-temperature water loops. Our mixing shunts and manifold assemblies blend high-temperature boiler outputs with cooler return water, preventing thermal damage to flooring and maintaining consistent zone comfort.
Municipal supply lines in North America often deliver water at pressures exceeding 80 PSI, risking damage to domestic appliances. Installing our lead-free certified pressure reducers helps lower inlet pressure to a safe, continuous 45-50 PSI, protecting household plumbing systems.
Multi-story commercial properties depend on balanced flow rates across every floor. Our dynamic HVAC valves and bypass air vents automatically adjust to pressure fluctuations, preventing dry operation in upper-floor heat exchangers and optimizing energy use.
Exploring the integration of smart controls and material science within fluid regulation.
The plumbing and heating industries are shifting toward intelligent hydronic balancing. Traditional mechanical valves are increasingly integrated with localized electronic sensors and actuator motors, communicating with building management systems (BMS).
These advanced assemblies monitor real-time pressure differentials, flow rates, and water temperatures. This allows building operator teams to identify pressure surges, locate blockages, and adjust flow distribution remotely, helping to lower building utility bills and prevent system downtime.
Regulatory bodies continue to tighten standards for heavy metal migration in potable water applications. This has driven the industry-wide adoption of lead-free brass alloys, premium DZR (Dezincification Resistant) materials, and food-grade interior coatings.
At Yuhuan Yongda, we track these evolving requirements closely. We offer lead-free brass formulations that maintain high machinability and mechanical durability, helping our global ODM partners keep pace with changing international compliance laws.
