Request PricingThe rapid pace of urbanization, structural transitions in manufacturing under the "Make in India" initiative, and extensive capital investments in central public utility projects have driven the demand for high-integrity fluid control technologies to historic heights. The Indian industrial valve market, particularly for structural isolation components such as gate valves, is shifting rapidly away from low-cost, uncertified gray-cast iron models to high-specification, forged copper alloys, DZR (dezincification-resistant) brass, and high-tensile stainless steel.
In key industrial belts—ranging from the petrochemical refineries of Jamnagar (Gujarat), the massive chemical and pharmaceutical corridors of Maharashtra and Telangana, to the textile processing clusters of Tamil Nadu—precision pressure control is paramount. Municipal water distribution frameworks, such as the *Jal Jeevan Mission*, are demanding components with higher service life thresholds, zero-lead composition compliance, and precise pressure seals. As a manufacturer catering to the global market, our engineering department designs gate valves that adapt to the distinct regional fluid properties of India, including high sediment ratios, temperature fluctuations, and variable input flow rates.
In high-rise construction across Delhi NCR, Mumbai, and Bengaluru, gate valves act as critical isolation units. Under high static head pressures, standard valves often fall victim to seal deformation and dezincification. High-grade brass gate valves with female threads offer robust service lifetimes, reducing municipal maintenance costs by up to 40% compared to typical iron-bodied gate assemblies.
Originally founded in 1996 as Yuhuan Yongda Plumbing Co., Ltd. (now operating as Yuhuan Yongda Fluid Control Co., Ltd.), we have established a strong presence in the global plumbing and valve industries. Located in Yuhuan, Zhejiang—known as the "China Valve Capital"—our enterprise integrates product design, material development, precision forging, surface finishing, assembly, and automated testing into one highly optimized manufacturing workflow.
Our manufacturing facility extends across a physical site area exceeding 45,000 square meters, yielding an actual usable production and warehousing space of 80,000 square meters. We operate more than 600 sets of advanced manufacturing and testing devices. This includes 80 units of dedicated high-precision CNC machines, multi-axis machining centers, and spectrographic material verification units. By managing raw ingot composition in-house, we guarantee chemical precision in our brass, copper, and stainless steel lines, catering to the strict demands of global regions including North America, Europe, and the growing industrial sectors of India.
To align with emerging market trends and premium international specifications, we launched our flagship product line under the registered brand Cokaren. Guided by the slogan "Keep Flowing, Keep Warming," Cokaren represents our commitment to advanced engineering, enhanced surface aesthetics, and precise metallurgical control. The brand delivers integrated hydronic heating and fluid management systems, designed to perform under challenging industrial operational conditions.
The reliability of a gate valve relies on its internal pressure seals and the quality of its alloy composition. Our engineering department enforces a strict quality policy: "Fine work, no leakage." This standard is supported by raw material analysis, cold-forging practices, and multi-stage air/hydrostatic pressure testing.
| Valve Type / Parameter | Material Configuration | Pressure Rating | Temperature Range | Primary Industrial Applications |
|---|---|---|---|---|
| Forged Brass Gate Valve | HPb59-1, CW617N, C37710 | PN16 to PN25 (232 to 362 PSI) | -20°C to 120°C | Municipal potable water distribution, HVAC headers |
| Dezincification Resistant (DZR) | CW602N / Lead-Free C46500 | PN25 | -10°C to 110°C | High-salinity coastal lines, sanitary systems |
| Stainless Steel Manifold Group | AISI 304 / 316 Grade | PN10 | Up to 95°C | Commercial hydronic distribution, floor heating |
| High-Calibrated Safety Valves | Cast Brass / Bronze Body | Set Range: 0.5 to 10 Bar | -20°C to 150°C | Boiler overpressure safety, closed loop HVAC safety |
By utilizing multi-spindle automatic transfer machines and high-tonnage hot forging presses, our gate valves achieve a homogeneous metal structure. This elimination of internal porosity prevents catastrophic failure under water hammer scenarios—a common issue in fast-growing municipal piping lines in cities like Chennai and Kolkata.
Unlike low-tier globe valves, Cokaren's brass gate valves offer an unobstructed flow channel when fully opened. This minimizes head loss and turbulences, which directly translates to reduced pumping energy costs. The wedge gate, machined using precision diamond tool lathes, sits flush against high-tensile PTFE or EPDM seats. This mechanical tolerance ensures class-A bubble-tight shutoff dynamics under zero-flow conditions.
Entering international markets requires adherence to recognized certification protocols. Our manufacturing plants operate under a certified ISO 9001:2015 Quality Management System, an ISO 14001:2015 Environmental Management System, and an ISO 45001:2018 Occupational Health and Safety Management System.
Our brass alloy compositions are checked via optical emission spectrometers to guarantee lead thresholds remain within regulatory parameters. For clean water applications, we produce lead-free brass formulations that meet the strict requirements of EN standards and global drinking water regulations. Additionally, our key products hold CE certification, qualifying them for integration into demanding industrial projects.
We work closely with Indian procurement partners to provide testing certificates, chemical analysis documents, and dimensional reports that align with local standards (such as IS 778 for copper alloy gate valves). Our quality assurance documents ease import clearances at major Indian ports like Nhava Sheva (Mumbai) and Chennai Port.

Integrates filtration, drain ports, and sensor wells into a single unit to optimize system balancing and tracking.
The fluid control industry is shifting toward smart automated controls and environmentally safe materials. Under the guidance of our design engineers, we are executing a technical roadmap that targets two key advancements:
Our smart electro-thermal actuators are engineered to link directly with municipal building management systems (BMS). Using low-voltage inputs (24v/230v), these actuators adjust valve gates automatically based on real-time sensory data, optimizing cooling cycles in industrial operations.
Responding to stricter global lead regulations, we have upgraded our induction melting lines to work with bismuth and silicon-bronze alternatives. This ensures we can provide non-hazardous, safe fluid control solutions for premium commercial drinking water networks in urban centers like Mumbai and New Delhi.

Yes. Our brass gate valves are rated up to PN25 (25 Bar / 362 PSI). This makes them suited for zones near pressure booster pumps and header lines in high-rise systems where vertical static head pressure can stress standard lower-grade valves.
Our company follows a zero-leakage quality policy: "Fine work, no leakage." Every gate valve undergoes multi-stage hydrostatic testing of the body and seat before packaging. In addition, our use of pure hot-forged brass bars eliminates internal micro-voids, ensuring long-term structural integrity.
