View DetailsSão Paulo represents the central engine of the Brazilian economy, demanding massive volume flow, continuous utility integration, and rigorous municipal pipeline management. With major entities like SABESP implementing vast structural revamps for the metropolitan water matrix, the procurement parameters for industrial isolation valves—especially robust gate valves—have surged dramatically.
Engineering departments, civil contractors, and municipal distributors across the state of São Paulo demand solutions that survive hard water mineral build-ups, dynamic thermal shifts, and mechanical wear. As a specialized manufacturer, we align our heavy-duty forged brass valves directly with these localized regional demands, guaranteeing zero leakage and uninterrupted services in high-density urban settings.
Whether navigating complex installations in commercial cooling loops along Avenida Paulista or integrating regional water utility lines in Campinas, Guarulhos, and SBC, our valves act as the silent structural foundations keeping fluid networks online and operational under all circumstances.
Key dynamics pushing high-specification valve procurement in the region:
Mitigating long-lead times, customs obstacles, and ensuring predictable procurement loops from China to the Port of Santos.
Our factories in Zhejiang sit in close proximity to Ningbo and Shanghai ports. We provide optimized container loading schemes, minimizing localized transit lag, enabling fast oceanic routes straight to the Port of Santos.
We output precise harmonized system code classifications (HS Codes), compliant packaging declarations, and full certification matrices to streamline Mercosur customs clearances and prevent container delays.
By using raw hot-forged brass and automated machining, we lower maintenance overheads, system downtime, and premature structural failure, translating to unmatched long-term investment returns.
A global leader in professional plumbing valves, environmental protection, and district heating systems.
Founded in 1996 and located in the famous "China Valve Capital" – Yuhuan, Zhejiang, Yongda Fluid Control has established a world-class manufacturing campus focusing on product design, development, production, and high-performance sales distribution.
Our corporate portfolio focuses on three core categories: brass valves, connection fittings, and modern hydronic HVAC solutions. Each solution highlights our structural commitment to environmental sustainability, durability, and leak-free reliability.
Under our progressive premium brand, Cokaren, we deliver refined designs, uncompromising metallurgical quality, and dedicated local support. Guided by our company policy "Fine work, no leakage", we help major global utilities and mechanical distributors scale their infrastructure seamlessly.
Ensuring complete hydraulic stability, structural integrity, and durability across high-pressure environments.
Cast bronze and brass valves often suffer from microscopic porosity issues, leading to stress fractures and weep leaks when subjected to heavy thermal fluctuations or pressure surges. Cokaren gate valves utilize hot-forging technology. This process optimizes the internal grain structure of the brass, maximizing tensile strength, yield limits, and eliminating physical defects under elevated pressures.
For potable water lines, municipal plumbing, and sanitary systems, preventing chemical contamination is crucial. We use certified high-grade lead-free and DZR brass materials (such as CW617N, C37700). These materials prevent zinc leaching in aggressive chemical networks, complying with global standards and matching local Brazilian sanitation regulations.
Equipped with solid wedge disks, heavy-duty packing glands, and dual PTFE seals, our gate valves offer bidirectional flow control and a long service life with low operational torque.

Comprehensive hydronic control systems designed for stability, low energy waste, and building safety.
Utilizing systems like the Y9021 Water Filter allows distribution networks to capture 98% of particulates, shielding downstream components from friction wear and operational failures.
For hydronic and manifold assemblies, mixing shunts (like the Y5020) stabilize internal fluids by regulating return temperatures, ensuring consistent indoor climates and piping protection.
Air pockets reduce thermal transfer efficiency. Our heavy duty venting valves (such as the Y9070) purge trapped air, preventing localized system damage and cavitation.
