As Malaysia accelerates its digital economy hub status and manufacturing bases across Selangor, Johor, and Penang, industrial flow control requirements have reached unprecedented heights. Rapidly growing sectors such as semiconductor cleanrooms, high-tier datacenters, pharmaceutical formulation facilities, and extensive commercial buildings demand extremely precise thermal distribution and fluid dynamics control.
Operating in a year-round hot and humid climate (A-type tropical rainforest climate) poses significant challenges to HVAC plant efficiency. Maintaining ideal humidity levels and preventing microbial colonization requires advanced chilled-water loops, domestic hot water disinfection, and precise thermostatic mixing loops. Traditional low-specification valves fail prematurely under continuous thermal cycling and high mineral water structures, leading to system downtime and costly emergency remediation.
Furthermore, Malaysia's strict Green Building Index (GBI) mandates high-efficiency mechanical systems. Green project developers now prioritize optimized water-mixing control loops and thermal optimization bypass systems to limit chiller load stresses and carbon footprints. Navigating this regulatory and climate framework requires advanced valve technologies built with longevity, lead-free composition, and precise actuation.
Understanding the chemistry, metallurgy, and hydrodynamic design requirements for reliable operations in Southeast Asian water supply systems.
Malaysian water supplies, particularly in coastal processing regions, contain high chloride concentrations that trigger dezincification in standard brass. We utilize CW602N, CW617N, and lead-free DZR brass alloys. This ensures that the zinc phase remains locked within the copper crystal structure, preventing structural leakage, scaling, and mechanical failures under high flow stress.
Our mixing shunt systems utilize high-sensitivity wax elements sourced from leading global suppliers. When temperature spikes occur, the wax expands dynamically within milliseconds, closing the hot or cold side to maintain outlet stability. This is crucial for avoiding thermal shock in commercial installations, hotels, and schools.
If the cold water inlet supply fails suddenly due to municipal pipe bursts or localized pressure drops, our anti-scald mixing valves automatically shut down the hot flow. This strict fail-safe mechanism conforms fully to EN1111 and ASSE 1017 international safety certifications.
Founded in 1996 and located in Yuhuan, Zhejiang—widely recognized as the "China Valve Capital"—Yongda has spent nearly three decades engineering world-class plumbing systems, brass valves, HVAC modules, and customized water management assemblies.
With a physical factory footprint stretching over 45,000 square meters and a total usable manufacturing area of 80,000 square meters, we export high-end fluid control products to over 20 countries. Under our premium brand Cokaren, we carry forward our commitment: "keep flowing, keep warming". We design and build components that ensure clean water flow, safety, and operational excellence.
Our production floor is powered by more than 600 sets of advanced manufacturing and metrology testing equipment, including 80+ dedicated multi-axis CNC machine tools that drill, thread, and profile valve bodies to micron-level tolerances. Through computerized robotic hot-forging and high-speed CNC precision machining, we maintain tight tolerance thresholds to eliminate micro-structural surface flaws.
Our quality management policy is straightforward and strict: "Fine work, no leakage." Every single mixing shunt, gate valve, and manifold assembly undergoes 100% pneumatic and hydrostatic high-pressure test routines. By verifying mechanical and seal integrity under pressures exceeding standard ratings, we protect downstream pipelines, boilers, and industrial plants from catastrophic fluid system failures.
Integrated control schemes managing heating, ventilation, air conditioning, and water purification circuits across commercial sectors.
A building’s energy distribution performance depends heavily on the compatibility of its mechanical linkages. A mismatch between manifold configurations, control valves, and air release groups can reduce system capacity and lead to energy waste. Our integrated system architecture coordinates heat pumps, water heaters, and hydronic networks to ensure continuous system balance.

Navigating importing and site compliance in Malaysia requires alignment with strict mechanical codes. Our entire production system and facility operations are certified under international framework standards, including ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety Management).
For municipal water integration, our brass product materials are formulated to support the licensing and registration process for SPAN (Suruhanjaya Perkhidmatan Air Negara). This aligns with water quality guidelines and SIRIM mechanical testing requirements. Additionally, our European CE-certified stainless steel and brass manifolds offer high structural resistance, making them ideal for government-backed infrastructure and luxury high-rise commercial developments.
