Engineered to ensure zero leakages in demanding multi-layer pipe distribution loops across Kuala Lumpur industrial networks.
Kuala Lumpur, as the financial and commercial heart of Malaysia, is undergoing an unprecedented architectural transformation. With mega-developments like the Tun Razak Exchange (TRX) and Merdeka 118 redefining the skyline, the demand for highly efficient HVAC, plumbing, and municipal water systems is surging. These projects operate under stringent green building standards, requiring durable, eco-friendly materials like multi-layer PEX-AL-PEX pipes and premium brass compression fittings.
Multi-layer pipes combine the benefits of metal and plastic, offering high temperature resistance and structural strength. However, the integrity of these networks depends entirely on the connection technology. Standard compression fittings must be carefully selected to avoid galvanic corrosion and stress corrosion cracking in KL's hot and humid tropical climate, which accelerates the degradation of low-quality brass alloys.
KL's municipal water systems occasionally experience chemical fluctuations. Standard brass fittings are susceptible to dezincification—a process that leaches zinc from the alloy, weakening the structural matrix and causing leaks. Yongda's custom DZR (Dezincification Resistant) brass compression fittings mitigate this risk, ensuring a service life of over 50 years.
Analyzing key shifts in high-precision plumbing systems, material optimization, and eco-friendly standards.
Globally, regulatory updates (such as North American NSF/ANSI 61 and European drinking water directives) are phasing out lead-content brasses. Exporters must provide CW617N or Lead-Free Eco-Brass options to comply with regional safety frameworks.
Multilayer composite pipes (PEX-AL-PEX, PERT-AL-PERT) are replacing traditional pure copper or galvanized iron pipes due to lower material costs, easy installation, and superior thermal properties.
Smart HVAC integration relies on manifold zoning and mixing shunts. Achieving thermal balance via optimized valves prevents system bottlenecks and optimizes green building ratings.
Brand Promise: Cokaren - "Keep flowing, keep warming". Focuses on developing residential and commercial water system components with refined designs and strict leak-proof technologies.
Founded in 1996 and located in Yuhuan, China's valve capital, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has grown into an industry-leading designer and manufacturer of brass valves, multilayer pipe fittings, and high-performance HVAC system components. With a usable building area reaching 80,000 square meters, our facility utilizes state-of-the-art automated forging, precision CNC machining, and rigorous testing setups.
Our products are engineered for medium-to-high-grade systems, focusing heavily on eco-friendly brass options that meet European and North American plumbing regulations. By exporting to over 20 countries, our technical team has accumulated deep regulatory and application-specific knowledge, helping developers in Kuala Lumpur and other key Southeast Asian hubs implement highly reliable infrastructure.
Our QC policy is simple but absolute: "Fine work, no leakage." To back this claim, every production lot of compression fittings and ball valves goes through pressurized air and hydro-leak test sequences, assuring complete safety when embedded in building matrices.

Looking ahead, the development of compression fittings is shifting toward smart IoT sensors embedded directly within manifold systems to detect pressure variances and micro-leaks in real-time. In terms of materials, we are continuously expanding our CW617N and lead-free eco-brass configurations to comply with international regulations while maintaining mechanical strength. For high-rise environments in Kuala Lumpur, our technical research focuses on enhancing the pressure-bearing capacity of the fitting collars to withstand excessive hydraulic shock load events.

How our multilayer fittings and custom brass valves resolve high-demand challenges in typical industrial configurations.
Kuala Lumpur's high temperature necessitates constant air conditioning. Large commercial developments utilize centralized cooling plants. In these systems, water distribution manifolds regulate flow across floor loops. Our HVAC valves, temperature regulators, and precision compression fittings ensure stable thermal zoning, reducing excessive compressor loading and electrical overheads.
Supertall residential developments require smart pressure-stage management. Multi-layer PEX systems paired with robust brass fittings prevent line ruptures and noise transmission. Our manufacturing process controls thickness tolerances strictly, allowing our products to withstand pressure spikes up to PN25 in multi-stage booster pump lines.
For research labs and processing facilities in Malaysia's industrial parks (e.g., Shah Alam, Klang Valley), fluid loops carry soft industrial wastewater or acidic runs. Our standard lead-free CW617N brass components and DZR fittings resist micro-crack corrosion, ensuring chemical process stability without leakage.
From CAD modeling to prototype casting and stress testing, our Yuhuan factory supplies turnkey custom designs tailored to complex project parameters in Southeast Asia.

Multilayer compression fittings establish a mechanical connection by securing the PEX-AL-PEX pipe between an internal insert (with EPDM O-rings) and a outer compression ring. This profile ensures a leak-free seal without requiring soldering, welding, or thread-sealant compounds. It significantly cuts down installation times and prevents thermal heat damage to surrounding structures.
For European distribution, we predominantly utilize CW617N brass (compliant with EN 12164/12165 standards). For high-end, strict drinking water systems, we supply Lead-Free Eco-Brass. For specialized, high-corrosion installations, we supply Dezincification Resistant (DZR) brass alloys that resist aggressive municipal water profiles.
Every single valve and manifold is subjected to automated hydraulic and air pressure test loops (typical testing includes 1.6Mpa testing pressure for 10-15 seconds) to ensure a 0% leak rate. We run fully certified laboratory facilities on-site to inspect raw material chemical makeup, thread accuracy, and pressure tolerance before shipping batches globally.
Generally, standard orders take 30-45 days from initial confirmation and drawing design approval. Fast-track options are available for standard components like compression adapters and straight double-threaded nipples, depending on current production scheduling and material availability.
