YQ981F Electric Liquid-Cooled Ball ValveOverview

The YQ981F Electric Liquid-Cooled Ball Valve is a high-performance fluid control unit specifically designed for new energy energy storage systems (ESS), data center liquid cooling units (CDU), and industrial cooling circulation systems. Driven by a low-power electric actuator, the valve body is made of high-quality stainless steel (e.g., CF8/CF8M), enabling precise regulation or shut-off of cooling media such as ethylene glycol solutions or silicone oil. Its compact and lightweight design makes it ideal for narrow piping spaces, serving as a core component for automated liquid cooling management and thermal efficiency optimization.

YQ981F Electric Liquid-Cooled Ball ValveCharacteristic

1.Superior Sealing Performance: Equipped with elastic compensated PTFE or modified RPTFE seats to ensure zero leakage even after frequent operations, effectively preventing coolant loss.

2.Low Pressure Drop Design: The Full Bore internal structure minimizes flow resistance, significantly reducing pump energy consumption and enhancing heat exchange efficiency.

3.High-Protection Actuator: The actuator reaches IP67 protection rating with excellent vibration and moisture resistance, supporting DC12V/24V or AC220V power inputs.

4.Strong Material Compatibility: Precision-polished valve body and internals offer high corrosion resistance, ensuring no scaling or contamination when used long-term in glycol solutions.

5.Real-time Feedback: Integrated active/passive signal feedback transmits valve position (Open/Close) to the control system for precise thermal management scheduling.
