Premium OEM and customized valve components engineered for low-pressure drops and positive sealing.
The global fluid dynamics landscape relies heavily on efficient backflow prevention and suction line integrity. A Ball Foot Valve functions as a specialized check valve installed at the base of a pump suction pipe. Its dual-role mechanism includes acting as a non-return barrier to prevent fluid column drain-back when the pump stops, while the integrated strainer blocks coarse particulates that could damage impeller assemblies.
Over the last decade, manufacturers have transitioned towards high-performance alloy structures, notably lead-free forged brass and electroplated nickel-brass compositions. Modern systems demand low cracking pressures and bubble-tight shutoffs under diverse thermal bands. Engineering shifts now prioritize hydrodynamic optimization, streamlining internal paths to minimize turbulence and net positive suction head (NPSH) losses.
Providing specialized HVAC systems, brass valves, and high-performance plumbing connections designed to meet North American and European industrial standards.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is situated in "China valve capital" – Yuhuan, Zhejiang. Spanning a usable facility footprint of over 80,000 square meters, we integrate raw material forging, precision CNC machining, and automated pressure testing under a unified quality infrastructure.
Our premium brand, Cokaren, operates under the core philosophy of "keep flowing, keep warming". Designed for high-end civil, commercial, and HVAC operations, Cokaren products feature refined structural profiles, strict tolerances, and upgraded flow performance for long-term domestic security.
Our operations comply with stringent environmental and safety frameworks. We maintain full system alignments: ISO9001:2015 for Quality Management, ISO14001:2015 for Environmental Protections, and ISO45001:2018 for Occupational Health and Safety Protocols.
Industrial valve procurement requires deep supply chain reliability to survive unpredictable logistics environments. At Yuhuan Yongda, we run more than 600 units of advanced manufacturing and testing devices, including 80+ units of high-accuracy dedicated CNC machines. This density of automated equipment enables rapid production scaling and batch-to-batch consistency.
By producing our own raw brass forgings, we strictly regulate chemical composition ratios, verifying copper content to prevent zinc leaching (dezincification resistance - DZR). This closed-loop fabrication setup shields global importers from volatile component shortages and ensures reliable dispatch times.
Different regions and industries demand custom fluid engineering approaches. Here is how our check valves and foot valves perform in various settings.
Installed at pump intakes to maintain prime, prevent system shock, and filter large debris. Yongda's heavy-duty brass construction withstands constant hydraulic cycling without thread degradation.
Our manifold assemblies, dynamic mixing shunts, and automatic air release valves work together in closed-loop systems, optimizing thermal distribution and protecting boiler circuits from pressure spikes.
Suction lines pulling from wells or storage ponds rely on foot valves to prevent water hammer and pump cavitation. The integrated stainless steel mesh filter ensures sand and gravel cannot enter the pump impeller.
Our corporate culture centers on detailed, precise execution. From tool selection to final dimensional checks, our quality control inspectors monitor physical specs on every production lot. We evaluate valve bodies for micro-fissures using pressurized nitrogen test chambers, identifying any leakage down to the lowest standard tolerances.
Through close collaborations with raw material suppliers, we procure top-tier brass alloys. These materials maintain structural durability across wide temperature ranges, providing dependable service in both hot water floor heating manifolds and deep-well water distribution lines.
Helping mechanical engineers, system designers, and wholesale buyers make informed industrial valve choices.
Premium components engineered to connect and control diverse commercial and residential piping projects.
