The assembly includes two resilient-seated shutoff ball valves with lever handles (QT suffix = quarter-turn ball valves), four test cocks, and an integral differential pressure relief valve that opens to atmosphere if the pressure differential between the two check valves drops to or below 2 psi, preventing back-siphonage and backpressure contamination. The LF (Lead-Free) designation confirms wetted surfaces contain ≤0.25% lead by weight, making it compliant with the Reduction of Lead in Drinking Water Act and California Prop 65 requirements. The FS suffix denotes full-flow, stainless steel internal components. Typical applications include commercial and industrial potable water supply, irrigation systems, boiler make-up water, and fire protection connections requiring high-hazard backflow prevention. Assembled in the USA as indicated on the box label.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
