YQ684F Pneumatic Three-Way Liquid Cooling Ball ValveCharacteristic

1、Efficient Three-Way Flow Design: Available in L-port or T-port configurations to precisely redirect coolant flow with minimal turbulence and energy loss.

2、Rapid Actuation: Equipped with a fast-acting pneumatic actuator that synchronizes with control systems for second-level response to thermal fluctuations.

3、High-Performance Sealing: Utilizes specialized PTFE or PPL seats compatible with glycol and deionized water, ensuring long-term leak-free performance.

4、Space-Saving Footprint: Compact and lightweight valve body design, ideal for integration into crowded liquid cooling cabinets and modular units.

5、Extreme Temperature Resilience: Built to operate reliably across a broad temperature spectrum, from extreme cold to high-heat computing environments.

6、Safety-First Engineering: Features an anti-static device and blow-out proof stem, enhancing operational security in high-current industrial or IT settings.
