YD81 Clamp quick-connect liquid cooling butterfly valve is a precision-engineered valve designed for high-cleanliness and long-cycle requirements in modern liquid cooling systems. Moving away from traditional fluoroplastic linings, this valve utilizes precision-ground metal-to-metal seating or integrated synthetic seals. Its primary advantage is eliminating the risk of "cold flow" deformation often associated with plastics under extreme temperatures. Using international standard tri-clamp connections, the YD81 provides a simplified, high-pressure, and low-maintenance solution for CDU modules and semiconductor cooling loops.

Feature
1、All-Metal/Hard-Seal Construction: Absence of plastic lining eliminates risks of aging, peeling, or media permeation, significantly extending service life under high-pressure cycles.
2、Second-Level Tool-Free Installation: Compatible with standard tri-clamps, enabling rapid assembly/disassembly by a single operator—a key component for modular maintenance.
3、High Thermal Shock Resistance: Without fragile plastic parts, the valve withstands wider coolant temperature fluctuations without seal failure due to thermal expansion.
4、Ultra-Thin Streamlined Disc: Hydrodynamically designed and polished disc minimizes local resistance (Kvs) when fully open, reducing pump workload.
5、High Purity Assurance: Made of high-grade stainless steel (e.g., 304/316L) with specialized cleaning; burr-free and oil-free to protect pure media like deionized water.
6、Lightweight & Compact: Significantly smaller than traditional wafer or flanged valves, effectively reducing the mechanical load on cooling pipe supports.
