Explore our core selection of OEM/ODM industrial brass valves, fittings, and thermal distribution components optimized for energy efficiency.
Delivering world-class plumbing valves and HVAC components since 1996 from China's Valve Capital.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is located in the famous "China Valve Capital" – Yuhuan, Zhejiang. As a premier industrial pioneer, we operate dynamic fluid systems manufacturing lines focusing on product design, modern development, precision CNC machining, and global exporting.
Our products span across three core lines: brass valves, specialized fittings, and HVAC control manifolds. We strategically target middle and high-grade segments, highlighting eco-friendly, lead-free brass engineering that meets strict North American and European plumbing safety guidelines.
How Modern Fluid Systems Tackle Pressure Fluctuations, Mechanical Failures, and Procurement Challenges
In modern commercial plumbing, municipal water networks, and industrial HVAC, controlling localized pressure surges is vital. An inline pressure regulator serves as the primary system guard against downstream over-pressurization. Industrial buyers frequently look for cost-effective manufacturing without compromising on metallurgical composition, dimensional accuracy, or spring responsiveness.
The term "cheap" in industrial sourcing does not mean compromised engineering. Instead, it refers to structural cost optimization through geographical sourcing advantages, advanced automation, and vertical integration. Operating in Yuhuan, China, allows Yongda Fluid Control to optimize brass extrusion, hot forging, and multi-spindle CNC machining processes. This helps lower unit costs for overseas buyers while maintaining compliance with international standards.
Inline pressure regulators function by balancing a spring-loaded diaphragm against the downstream pipeline pressure. If the downstream pressure rises, the diaphragm moves upward, compressing the spring and throttling the valve orifice to reduce flow. Conversely, if pressure falls, the spring pushes down to open the path, maintaining a stable set pressure.

| Diaphragm Material | Standard NBR Rubber | EPDM with Nylon Reinforcement | Thermal stability up to 120°C; prevents cracking. |
| Sealing Architecture | Single O-Ring Seal | Dual EPDM Seals + Piston Guide | Eliminates internal bypass leaks ("Fine work, no leakage"). |
Building on our manufacturing expertise, Cokaren is our premium brand dedicated to high performance and refined product design. Driven by the brand promise "keep flowing, keep warming", Cokaren focuses on smart residential water distribution systems, underfloor heating manifolds, and custom pressure regulation valves. We aim to grow Cokaren into a globally recognized brand by delivering durable, reliable, and aesthetically refined products.
Water distribution systems are moving toward digitalization and integration. Future installations will rely on intelligent nodes that combine filtration, automatic air venting, smart thermal control, and pressure regulation in a single unit.
Developing hybrid valves that combine pressure regulation with integrated strainers and smart flow monitoring sensors.
Expanding the use of advanced eco-friendly, lead-free brass across all product lines to meet evolving global drinking water standards.
Linking thermal actuators, manifolds, and balancing valves to centralized, IoT-enabled building management systems.
We design high-performance control systems that regulate temperature, manage pressure, and maintain steady flow across residential and industrial networks.
An efficient energy distribution system requires precise pressure control, reliable shut-off mechanisms, and automated balancing. Our engineered line of brass manifolds, mixing units, and venting valves work together to prevent heat loss, eliminate pipeline air pockets, and protect sensitive components from sudden pressure surges.

How we ensure reliable performance and international standards compliance in every valve batch.
Our production plants run on a simple operating principle: "Customer first, Quality based". With our policy of "Fine work, no leakage", we subject 100% of our inline pressure regulators, ball valves, and manifolds to hydrostatic and pneumatic pressure testing. This testing helps prevent structural micro-fractures and seals against leaks before the valves leave our warehouse.
Yuhuan Yongda maintains a complete quality control structure, backed by internationally recognized management system certifications:
