Explore our initial curated collection of high-durability flow control components, engineered for HVAC, plumbing, and distribution systems globally.
In modern industrial plumbing and large-scale commercial fluid distribution systems, efficiency and reliability are paramount. Grooved piping systems have revolutionized the market by offering rapid assembly times, vibration isolation, and superior joint stability. A key component of these modern piping configurations is the grooved ball valve. As a critical regulatory device, it controls fluid circulation across high-rise HVAC loops, municipal water works, fire protection systems, and petrochemical pipelines.
Unlike traditional threaded or welded connections, a grooved ball valve is designed with integral grooves at the inlet and outlet ports. These grooves allow direct coupling using standardized mechanical housing clamps. The result is a robust, leak-free connection that can handle thermal contraction, seismic shifts, and dynamic pressure variations. The global demand for these valves is experiencing rapid expansion, spurred by the need to retrofit aging infrastructure with modern, energy-efficient components. High-precision manufacturing and compliance with global standards, particularly CE Certification, are non-negotiable requirements for tier-one project delivery.
Maintains absolute operational safety under high-pressure scenarios, ensuring minimal head loss and optimized laminar flow profile.
Eliminates welding, threading, or flanging requirements, cutting down installation time by up to 60% relative to conventional systems.
The mechanical coupling configuration inherently absorbs pipe noise and limits the spread of acoustic vibration across pump manifolds.
For any fluid control device destined for the European Economic Area (EEA), CE Certification is a core legal prerequisite. It is not merely a label, but a verification that the product conforms to strict health, safety, and environmental protection standards. For pressure-retaining devices like ball valves, this falls under the Pressure Equipment Directive (PED) 2014/68/EU.
To earn a CE mark, a grooved ball valve factory must implement a robust testing regime. Key verification criteria include:
In the international industrial landscape, localized industrial clusters offer significant advantages. Yuhuan, located in Zhejiang Province, is recognized globally as the "China Valve Capital". This region hosts a mature vertical supply chain where raw material procurement, precision hot forging, high-speed multi-axis CNC machining, surface finishing, and assembly testing occur within a single industrial ecosystem.
This concentration translates directly to customer value. By eliminating geographical delays in raw material transport and component processing, manufacturers based in Yuhuan achieve unparalleled production speeds. Standardized processes, advanced mold design capabilities, and shared metallurgy labs minimize cycle times for bespoke custom designs (OEM/ODM). Furthermore, the proximity to major deep-water ports like Ningbo and Shanghai guarantees fluid logistics and reliable global container routing. This localized ecosystem ensures that our supply chain remains highly resilient against macroeconomic disruptions.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is located in Yuhuan, Zhejiang. As a specialized plumbing valve enterprise, we focus on integrated product design, development, testing, and volume supply. Our products span three primary categories: brass valves, plumbing fittings, and HVAC solutions, engineered for mid-to-high grade systems with an emphasis on environmental protection.
Under our new brand Cokaren, we are dedicated to delivering refined designs, premium quality, and reliable services. Cokaren’s promise is simple: "keep flowing, keep warming", bringing comfortable hydronic and flow performance to homes and commercial spaces globally.
Transitioning toward completely lead-free, dezincification-resistant (DZR) brass alloys to comply with upcoming strict drinking water regulations globally.
Integrating smart motorized actuators with real-time sensory feedback loops, reporting fluid temperature, flow volume, and pressure drops.
Optimizing inner cavity geometries through 3D CAD modeling and finite element analysis to achieve maximum Cv ratings and minimum turbulences.
Our components act as integral blocks within complex, multi-stage commercial hydronic loop designs.

Our CE Certified grooved ball valves and brass components are designed for direct installation in demanding environments:
Optimized for large central water chillers and boiler header installations. The grooved interface allows mechanical crews to isolate pipelines and swap equipment without hot-work permits or structural welding lines.
Our precision underfloor manifolds and temperature controllers distribute uniform temperature parameters in colder European and North American climates, ensuring high energy-use efficiency (COP).
Perfect for raw cooling media management in automated assembly lines and cleanroom micro-filtering infrastructure. Double O-ring shaft seals and nickel-plated elements deliver long-term corrosion resistance.
We maintain an integrated management model that has achieved three crucial system certifications: ISO9001-2015 for quality management systems; ISO14001-2015 for environmental compliance and resource management; and ISO45001-2018 for occupational health and safety standards. Our Quality Policy remains direct: "Fine work, no leakage." Every valve segment is pressurized and logged in our system before packing.
Our complete catalog covers diverse commercial needs, from underfloor manifolds to certified residential and industrial water management components.
