Get Specs & QuotesOperating a modern district heating (Π‘Π¦Π) and utility water infrastructure in regions like Siberia, the Urals, and the European plain of Russia demands piping and brass fittings with unparalleled mechanical tenacity. These components must withstand thermal expansion cycles ranging from -40Β°C in winter to +30Β°C in summer. The intense temperature fluctuations of the Russian heating season impose extreme mechanical stress on localized distribution stations.
Yuhuan Yongda's brass composition incorporates trace elements of elements like Tin and Nickel, aligning with CW617N and HPb59-1 standards. This limits dezincification, ensuring that internal piping interfaces do not decay prematurely under highly mineralized boiler waters. Our components prevent micro-stress fracturing under water hammer conditions commonly caused by rapid pressure shifts in urban residential networks.
From Saint Petersburg's premium housing to Vladivostok's industrial ports, our fittings serve essential infrastructural roles.
With domestic real estate expansion driving the need for smart, energy-efficient apartments, our multi-port manifold and brass bypass systems ensure balanced hot-water circulation through sub-zero winter spells, optimizing heat transfer efficiencies across Moscow's high-rises.
Powering primary and secondary loops of domestic and industrial boilers. Capillary soldering fittings and temperature control valves are critical for thermal safety, ensuring hot water is mixed and distributed without system failure.
Heavy-duty hose bibcocks, garden hose quick connectors, and threaded unions serve as key points in processing facilities where high chemical compatibility and corrosion resistance to aggressive fluids are mandatory.
Founded in 1996 in Yuhuan, Zhejiangβthe recognized "Valve Capital of China"βYuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved into a global titan of plumbing valve systems. Operating a massive factory footprint spanning over 45,000 square meters with an actual usable floor area reaching 80,000 square meters, we maintain full control over the metallurgical and mechanical life-cycles of our products.
Our premium brand, Cokaren, operates under the brand promise: "Keep flowing, keep warming". Our mission is to integrate top-tier water system accessories to establish safety, durability, and comfort in residences and commercial architectures globally.

Discharges air pockets in heat-source pumps to secure water flow.
Stabilizes fluid temperature to prevent pipe thermal shock.
Intelligently adjusts underfloor zoning elements automatically.
Integrated temperature-monitoring drain/filter valve.
Fluid engineering is shifting rapidly towards high sustainability and automated integration. In the Russian construction market, new requirements prioritize materials that do not degrade or deposit heavy metals into the municipal water cycles. Yuhuan Yongda's research division is pioneering several strategic technological pathways:
Leveraging Yuhuan's premier industrial ecosystem to ensure rapid bulk supply for critical Russian housing projects.
Industrial procurement in Russia requires reliable supplier capabilities to handle raw material fluctuations and strict freight timelines. Our facilities house over 600 sets of automated forging, CNC machining, and hydro-testing apparatuses, backed by dedicated raw copper stock-hedging programs.
We leverage direct China-Europe freight trains (Sino-Russian Rail Express) departing from major Zhejiang hubs. This allows us to deliver heavy containers of brass valves and pipe fittings straight to Moscow, Kazan, and Novosibirsk in under 20 days. This supply route bypasses traditional maritime blockages, shielding our Russian distributors from volatile logistics and securing continuous construction operations.
Our quality assurance policy remains strict: "Fine work, no leakage." Every single valve is subjected to high-pressure air and water tests under water, mitigating installation risks on-site.
Full compliance validation for regional safety and operational approvals across the Eurasian Customs Union.
Our product lineup meets strict Eurasian Customs Union standards, clearing necessary customs clearances and allowing seamless incorporation into public tender frameworks in Russia.
Our environmental management guidelines reduce carbon footprint during smelting and forging stages, prioritizing ecological safety and resource efficiency.
Our quality and occupational safety standards are built directly into our assembly flow, assuring consistent batch quality and on-schedule shipping schedules.
