Premium solutions customized for global HVAC systems, industrial loops, and PEX infrastructure projects.
In modern liquid and gas infrastructure, pressure reduction is not simply a safety metric—it is the cornerstone of energy optimization and operational longevity. Municipal water grids, chemical processing lines, and commercial high-rise building distribution systems rely on robust pressure reducing valves (PRVs) to maintain steady domestic flow rates while protecting downstream components. Fluctuating incoming supply lines require smart, self-acting regulators capable of managing high delta-P values without inducing cavitation or metal erosion.
Globally, the push for lead-free compliance and dezincification-resistant (DZR) alloys has transformed standard manufacturing models. Standard CW617N brass is rapidly transitioning to eco-friendly, bismuth-stabilized or low-lead brasses to comply with NSF/ANSI 61 and EU drinking water mandates. In China, industrial zones like Yuhuan in Zhejiang have evolved into massive hubs combining raw casting, precision forging, CNC machining, and automated pressure testing under strict quality assurance frameworks.
A proven track record of exporting premium-grade brass valves, manifolds, and HVAC controls worldwide.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda plumbing Co., Ltd.) was founded in 1996 and is located in the "China valve capital" – Yuhuan, Zhejiang. As a prominent, professional plumbing valve enterprise, we focus on integrated product design, development, production, and sales.
Our products are classified into three primary categories: brass valves, plumbing fittings, and specialized HVAC systems. With a target focus on the mid-to-high-end market segment, we engineer products with a primary focus on environmental safety, leading to substantial growth in demanding markets including North America, Europe, and Asia.
With an production facility area of over 45,000 square meters (actual usable space reaching 80,000 square meters), our plant is equipped with more than 600 sets of advanced manufacturing and testing devices, including 80+ special precision machine tools. This robust technological footprint allows us to meet diverse customer specifications and OEM standards globally.
Cokaren, the newly established premium brand of Yuhuan Yongda Fluid Control Co., Ltd., is dedicated to developing products with a more refined design aesthetic and superior mechanical quality. Built with engineering precision, Cokaren delivers absolute reliability to system designers and end-users alike.
Our brand promise, "Keep flowing, keep warming", reflects our desire to design water system accessories that bring comfortable heat distribution and seamless, noise-free utility control into modern homes and industrial properties.
As Cokaren implements its strategy to build a dynamic, customer-centric enterprise, we continue to push boundaries to establish our reputation as a trusted, world-class fluid technology brand.
Struggle, Enterprising, Pragmatic, and Innovative. We seek perfect alignment between corporate growth and individual career fulfillment.
"Fine work, no leakage." Under ISO9001, every raw piece of brass undergoes extensive forging, machining, and 100% pneumatic testing.
Our facilities are fully certified under ISO9001:2015, ISO14001:2015 (Environmental Management), and ISO45001:2018 (Occupational Health and Safety).

Standard mechanical pressure reducing valves rely on springs and balanced diaphragms to limit downstream pressure. While robust, these systems fail to adjust dynamically to real-time grid conditions, seasonal temperature fluctuations, or digital facility commands. Yongda's future product roadmap is centered around IoT-enabled electro-hydraulic systems, linking actuators to precision flow sensors.
