The Ames 3 Inch Double Check Backflow Preventer Fire Valve Assembly isolates commercial and residential fire protection systems to protect municipal water supplies from contamination. It installs directly into standard 3-inch piping to stop backflow events driven by backpressure or backsiphonage. Built with dual check valves featuring a low pressure drop design, the unit maintains consistent water flow during operation while blocking stagnant system water from entering potable lines.
This assembly complies with NFPA 13 installation requirements to satisfy life safety mandates for fire protection systems. Forged steel Outside Stem & Yoke (OS&Y) gate valves offer clear visual operational feedback on valve status, which helps simplify mandatory annual testing and cuts down on inspection downtime.

- FxG OS&Y Gate Valves: Features forged steel Outside Stem & Yoke valves for precise system isolation without disrupting downstream flow or hiding operational status.
