Yongda
Engineered for high performance, thermal efficiency, and zero-leakage configurations.
For mechanical specifications, municipal infrastructure, and large-scale industrial fluid systems, securing certified flow control devices represents the cornerstone of operational stability.
Delivering precision-engineered fluid control components globally from Yuhuan, the valve capital of China.
Our design engineering roadmap focuses on durability, environmental compliance, and smart automation.
Transitioning production to lead-free brass compliance (NSF/ANSI 61 and California Prop 65). Our proprietary thermal forging ensures zero cracking and minimum zinc migration.
Developing hydrodynamic spring-closing check valves. By closing prior to flow reversal, our system cuts out transient pressure spikes and protects plumbing joints.
Integrating intelligent linkage with room stats and boilers under the Cokaren brand ecosystem. Helping users lower energy use through smart, automated temperature zoning.
As Yongda’s premium brand, Cokaren is dedicated to developing products with a more refined appearance, tighter tolerances, and better material quality. Our brand promise, "keep flowing, keep warming," guides our focus on creating reliable plumbing, manifold, and heating parts that make homes comfortable and safe.
We balance our business growth with employee well-being, driving an innovative work culture that ensures high quality standards. Our manufacturing team operates under a simple, strict policy: "Fine work, no leakage."
Our core energy distribution designs route fluid efficiently, regulate system temperatures, and filter impurities.
Our manufacturing operations meet strict ISO quality, safety, and environmental standards.
Every single valve is pressure tested before packaging. We inspect seals under low-pressure gas and high-pressure water to confirm zero leakage. By tracking production batches back to raw material ingots, we prevent metallurgical defects like porosity and stress cracks.
This thorough testing process ensures our foot valves, safety valves, and manifolds deliver dependable service year after year.
