YQ11F 1-PC Liquid Cooling Ball ValveOverview

The YQ11F 1-PC Liquid Cooling Ball Valve is a compact control valve specifically designed for data center server liquid cooling systems, power battery heat dissipation, and various precision cooling circulation pipelines. Featuring a one-piece investment casting structure, this valve minimizes potential leak points at body connections, ensuring the safety of liquid cooling systems in high-precision operating environments. Its core design focuses on low flow resistance and lightweight construction, enabling precise on-off control of cooling media (such as deionized water or ethylene glycol solutions). Due to its compact structure and reliable sealing, it is an essential fluid control component in modern high-computing equipment and new energy storage system cooling solutions.

YQ11F 1-PC Liquid Cooling Ball ValveCharacteristic


1.The 1-PC integral structure design features a monolithic casting body that eliminates redundant joint surfaces, providing high structural strength and superior anti-leakage performance for space-constrained liquid cooling environments.

2.The optimized flow design ensures internal passages are hydrodynamically optimized to provide high flow capacity and extremely low pressure drop, effectively reducing pump power consumption and improving system heat dissipation efficiency.

3.Excellent material compatibility is achieved by using CF8 or CF8M stainless steel for the body and modified PTFE for the seats, ensuring corrosion resistance and zero contamination of the cooling medium during long-term operation.

4.The lightweight and compact design is specifically engineered for liquid cooling racks and compact modules, with a small footprint and low weight that facilitate easy installation within densely wired server cabinets.

5.High-reliability sealing performance utilizes a precision-ground ball and floating seat structure that supports a 1000 WOG pressure rating, maintaining bubble-tight shut-off even under frequent operation to prevent coolant loss.
