The YQ21 Internal and External Thread Liquid Cooling Ball Valve is a specialized control component designed to meet diverse connection requirements in liquid cooling circuits. Its unique "Male-to-Female" thread structure allows it to act as both a connector and a terminal control valve, directly linking equipment and piping networks. It is widely used in energy storage container cooling loops, liquid-cooled charging piles, and immersion cooling systems. By reducing the need for extra adapters, it minimizes potential leak points and optimizes integrated liquid cooling designs.

Feature
1、Flexible Thread Configuration: The unique male-to-female combination simplifies piping layouts, especially in space-constrained environments where direct connection to sensors or hoses is required.
2、Targeted Sealing Optimization: Seats and seals are made from specialized modified materials that withstand long-term exposure to hydrofluoroethers and glycol solutions, ensuring stability for over a decade.
3、Minimal System Pressure Drop: The full-bore design and smooth internal channels minimize local resistance, ensuring efficient circulation of the cooling medium.
4、Superior Corrosion Resistance: Precision-machined from stainless steel (CF8/CF8M), the body remains rust-free and prevents particle shedding, maintaining the purity of the cooling system.
5、Effortless Operation: The combination of a precision-ground ball and low-friction seats ensures minimal operating torque even under extreme temperature fluctuations.
6、High-Strength Structural Design: Features a blow-out proof stem and reinforced wall thickness to withstand pressure surges during system startups and shutdowns.
