View Tech SpecsHanoi, the administrative capital of Vietnam, is witnessing an unprecedented wave of urban densification and industrial transformation. From high-tech assembly factories in the Thang Long Industrial Park and Quang Minh Industrial Zone to modern commercial developments in Tay Ho and Nam Tu Liem districts, the demand for high-reliability HVAC, domestic sanitary hot water systems, and piping equipment has scaled exponentially. The regional sub-tropical climate, characterized by extremely high humidity levels and sharp seasonal temperature swings, poses severe challenges to structural piping.
In this challenging environmental landscape, standard grade alloys quickly fall prey to dezincification and galvanic corrosion. Our dedicated Pipe Series, manufactured using superior brass compositions, directly mitigates these local variables. In high-density towers and cooling distribution arrays throughout Hanoi, these control systems maintain hydraulic balancing, prevent scale formation, and guarantee consistent operational efficiency for both low-energy building designs and industrial process piping.
In the context of the global green building revolution, smart automation is reshaping traditional plumbing designs. Current dynamics focus heavily on energy optimization, precise flow limitation, and materials that adhere to rigid lead-free parameters.
Transitioning from manual balancing valves to dynamic, motorized pressure independent control valves (PICVs) that adjust dynamically to load fluctuations.
Adhering to strict European and North American sanitary laws by incorporating lead-free silicon brass alloys across domestic potable pipelines.
Equipping standard thermal manifolds with automated electro-thermic actuators and digital controllers for precise, remote cloud-based adjustments.
Established in 1996 in Yuhuan, Zhejiang—the recognized valve capital of China—Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has matured into a premier global designer, developer, and manufacturer of brass valves, custom fittings, and HVAC manifolds.
Our operation is anchored by our high-end brand, Cokaren, whose guiding philosophy is "keep flowing, keep warming". Our production catalog spans heavy industrial underfloor heating assemblies, multi-turn brass angle valves, motorized actuators, and critical hydraulic mixing systems designed to satisfy stringent quality thresholds globally.
We pride ourselves on our highly dynamic manufacturing processes, leveraging a suite of more than 600 advanced CNC centers and specialized quality-testing machines. This comprehensive setup empowers us to export consistently to over 20 nations across Europe, North America, and emerging markets in Southeast Asia like Vietnam.
Our integrated system controls the distribution of energy in modern residential and light commercial buildings. The flow diagram below illustrates how our manifolds, thermal actuators, and mixing valves function systematically.
Our Y9021 Water Filter screens 98% of particulates and suspended sand, keeping internal valves clean, preserving seals, and preventing system blockage.
Using the Y5020 Mixing Shunt, return fluids are dynamically mixed with hot water lines to stabilize temperatures, protecting underlying floor circuits from thermal stress.
Smart actuators coupled with brass manifolds (Y1001) allow for automatic adjustments in individual rooms based on smart thermostat readings.
