Rack Quick Disconnect Module Double-Shutoff Valve Leakage Standards – Official Technical Overview & Hardware Datasheet

EXECUTIVE SUMMARY

The Rack Quick Disconnect Module Double-Shutoff Valve Leakage Standards (RQDM-DSV) establishes a new benchmark for fluid containment integrity in carrier-grade telecom rack environments. Engineered for mission-critical liquid-cooled and dielectric-fluid systems, this module integrates dual redundant shutoff valves with precision leakage control, ensuring zero-downtime operation and environmental compliance. This datasheet outlines the hardware architecture, performance specifications, and compliance framework for OEM integration.

ARCHITECTURE & CHASSIS DESIGN

The RQDM-DSV is housed in a compact 1RU chassis constructed from marine-grade aluminum with corrosion-resistant coating. The double-shutoff valve assembly features two independent, spring-loaded poppet valves arranged in series, providing fail-safe isolation upon disconnection. The module includes integrated leak sensors, pressure transducers, and a local status LED array. Quick-disconnect couplings are rated for 10,000 mating cycles and are compatible with standard 3/8-inch and 1/2-inch fluid lines.
