YP21X Micro Air Release Valve for Liquid CoolingOverview

The YP21X Micro Air Release Valve is a compact automatic venting device designed specifically for data center liquid cooling modules, server cold plates, and Cooling Distribution Units (CDU). During the circulation of the liquid cooling system, small amounts of accumulated air can create air locks, reducing heat exchange efficiency and causing pump cavitation. Featuring a lever-float mechanism, this valve senses fluid level changes in real-time, automatically discharging micro-bubbles under system operating pressure and closing tightly when liquid reaches the port, ensuring the cooling loop remains fully filled with liquid.

YP21X Micro Air Release Valve for Liquid CoolingCharacteristic


1、High Sensitivity Venting: Specifically designed for the micro-bubbles generated in liquid cooling loops, using lever principles to amplify buoyancy for precise action even with minimal air buildup.

2、Venting Under Pressure: Unlike standard valves, it supports continuous air release while the system is at full operating pressure, effectively eliminating "air lock" phenomena.

3、Anti-Spurt & Leak-Proof: Precision-ground internal components and high-resilience rubber seals ensure only air is released without liquid spray, keeping the cabinet environment dry.

4、Ultra-Compact Structure: The extremely small footprint fits inside servers or compact cooling modules without interfering with other electronic components.

5、Stainless Steel Purity: The stainless steel body resists long-term corrosion from deionized water or glycol, ensuring no impurity precipitation and maintaining coolant purity.

6、Anti-Clogging Design: Features a specialized dust cap or anti-clogging passage to prevent environmental dust or coolant crystallization from affecting venting performance.
