YD71F Wafer Fluorine-Lined Liquid Cooling Butterfly ValveOverview

The YD71F Wafer Fluorine-Lined Liquid Cooling Butterfly Valve is a fluid control component designed specifically for highly corrosive or ultra-pure cooling media (such as HFE, PFPE, and special chemical coolants). Utilizing a comprehensive fluorine-lining process, the internal cavity and the disc are fully encapsulated in high-performance fluoroplastics, completely isolating metal parts from the medium. The wafer design significantly compresses the installation footprint, making it ideal for semiconductor cooling, pharmaceutical thermal management, and specialty energy storage systems requiring extreme purity and corrosion resistance.

YD71F Wafer Fluorine-Lined Liquid Cooling Butterfly ValveCharacteristic

1、Universal Corrosion Protection: Fully lined with F46 or PFA, it resists almost all strong acids, alkalis, and chemical coolants except for molten alkali metals.

2、Ultra-High Media Purity: The stable lining prevents ion leaching, ensuring no secondary contamination of the coolant and protecting sensitive electronic equipment.

3、Bi-directional Zero Leakage: The centerline structure combined with an elastic seat achieves tight sealing in both directions even under frequent operation.

4、Ultra-Thin Space Design: The classic wafer structure features short face-to-face dimensions and low weight, reducing mechanical loads on liquid cooling cabinet piping.

5、Smooth Operating Torque: The stem features a specialized sealing structure with self-lubricating bushings, ensuring consistent manual or pneumatic operation.

6、Full-Flow Compensation: The streamlined disc minimizes flow resistance when open, reducing pump energy consumption and maximizing system efficiency.
