Yongda
Engineered to withstand intense mechanical stress and extreme thermal variations common in Central Asian pipeline networks.
Kazakhstan represents the economic hub of Central Asia, possessing enormous deposits of natural minerals, petroleum, and natural gas. This geographic abundance necessitates heavy-duty infrastructure networks. Across fields like the Tengiz oilfield, Karachaganak, and Kashagan, fluid transport infrastructure is subject to immense operational demands.
One-way check valves represent a vital line of defense in these processing setups. By allowing fluid flow in only one direction, check valves prevent devastating reverse flow back into pumps and compressors. In regions where temperatures range from -40°C in winter to over +40°C in summer, valves must resist thermal contraction, high pressure spikes, and sour gas corrosion.
Furthermore, Kazakhstan's municipal utility sector in urban centers like Almaty, Astana, and Shymkent is undergoing major modernization. Municipal heating grids require specialized brass check valves and underfloor manifold setups that comply with strict EAEU (Eurasian Economic Union) safety guidelines.
Founded in 1996 and located in the "China valve capital" – Yuhuan, Zhejiang, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda plumbing Co., Ltd.) has developed into a premier B2B manufacturer specializing in high-grade fluid control systems.
Our extensive portfolio spans three major product segments: brass valves, fittings, and HVAC systems. Positioned in the mid-to-high-grade segments, our products highlight environmental sustainability, performance reliability, and robust design. Over the last two decades, Yongda has become a key supplier across North America, Europe, and central Asian markets like Kazakhstan.
To deliver a more refined aesthetic and premium performance, our modern brand Cokaren carries the promise: "keep flowing, keep warming". Cokaren is dedicated to designing accessories that guarantee safety, warmth, and reliable operations.

We consistently strive to develop organizational capacity, improve employee welfare, and ensure alignment between business growth and personal happiness.
Yongda strictly follows international manufacturing benchmarks to guarantee the highest safety performance. Our factory operations and product lines are backed by the following management certifications:
Specialized components designed to handle municipal district heating, floor heating, and domestic water sanitation requirements in highly fluctuating continental climates.
First line of defense in domestic sanitation, filtering 98% of pipeline impurities.
Controls hot and cold water inflow and outflow in boilers, utilizing a spherical spool.
Discharges excess air in heat systems to maintain steady operating pressure.
Mixes pipeline supply streams to stabilize system temperatures and protect pipe joints.
Integrates heating components to dynamically adjust multi-room ambient temperature.
Discharges water impurities, controls manifold back-ends, and monitors water temperature/pressure.
Distributes hot water flow to individual rooms to achieve micro-zoned climate control.
Building highly durable products to minimize maintenance overheads in demanding B2B heating systems.
Analyzing logistical links, raw material superiority, and international standards integration.
Proximity to Xinjiang land ports (Khorgos, Alashankou) allows direct rail and road shipments from Chinese manufacturing centers directly to Nur-Sultan or Almaty. This route offers shorter transit times compared to European maritime freight.
Our factories utilize high-density forging technology to eliminate internal porosities in brass alloys. Our valves perform reliably under intense freeze-thaw cycles and severe pressure adjustments.
By adjusting lead ratios and utilizing CW617N or DZR (Dezincification Resistant) brass alloys, we manufacture check valves that resist brittle failure in environments that regularly plunge below freezing.
Technical solutions and procurement answers for B2B pipeline buyers and engineers.
Kazakhstan relies on centralized municipal district heating. The enormous size of these networks creates risk of severe pressure dropbacks. Standard check valves prevent hot media from backflowing into regional feed lines when pumps shut down, preventing water hammer damage.
Valves must comply with EAC marking protocols defined by the Eurasian Economic Union (EAEU). Our manufacturing pipelines strictly respect TR CU 010/2011 (Machinery Safety) and TR CU 032/2013 (Pressure Equipment Safety) regulations.
Our factory uses over 600 sets of advanced testing equipment to run pressure inspections on every production run. Our strict quality policy ensures that each brass valve leaving the production floor undergoes rigorous air/water sealing tests.
Yes. Leveraging our 45,000-square-meter facility and professional R&D team, we customize valve dimensions, alloy compositions, and connection standards (NPT, BSP, or sweat connections) to match localized pipeline projects.
