The YQ11 Internal Thread Liquid Cooling Ball Valve is a small-bore fluid control component specifically designed for compact liquid cooling circulation systems. Utilizing a two-piece or three-piece body structure connected via female threads, it is widely used in immersion cooling servers, energy storage battery cooling branches, and laboratory temperature control units. The design focuses on flow path smoothness to minimize pressure loss and uses highly stable materials to ensure zero leakage and low operating torque when in long-term contact with various coolants, such as synthetic oils and hydrofluoroethers.

Feature
1、Excellent Sealing Compatibility: Optimized for various insulating oils and fluorinated liquids commonly used in the industry, offering outstanding chemical resistance.
2、Low Flow Resistance: Full-bore design ensures high-speed coolant passage, minimizing pump energy consumption and enhancing overall cooling efficiency.
3、Compact Design: Small footprint ideal for installation within space-constrained liquid cooling cabinets and modular piping.
4、High-Precision Threading: Complies with international standards (G, NPT, PT, etc.), with smooth surface finishing to ensure easy and tight installation.
5、Wide Temperature Range: Operates reliably across a broad temperature spectrum (-40°C to 130°C), maintaining material stability under extreme fluctuations.
6、Long-Life & Low Maintenance: Features a blow-out proof stem and low-friction seats to significantly extend the operational lifespan of the valve.
