6" Double Check Detector Valve With OSY by Ames Backflows

Safeguard commercial and residential potable water supplies against contamination from cross-connections with the Ames Backflows 6" Double Check Detector Valve with OS&Y. Engineered for high-demand fire protection systems, including sprinkler and standpipe lines, this heavy-duty assembly handles fluctuating system pressures to maintain reliable backflow prevention. It satisfies vital plumbing and fire safety compliance requirements by integrating an active monitoring system for low-flow conditions.

The unit features an integrated detector check to monitor minor flows and potential leaks for early backflow detection. Built with an Outside Stem and Yoke (OS&Y) design, the valve provides an immediate visual indication of whether the valve is open or closed during routine inspections. Crafted from high-grade, corrosion-resistant materials, the assembly endures harsh operational environments while requiring minimal ongoing maintenance.
