Product Details

Zurn Industries 6-350ADAOSYPIFG

The 6'' 350ADAOSYPIFG Double Check Detector Backflow Assembly, with post indicator and OSandY gate valves with flanged inlet connection and grooved outlet connection, protects against both back siphonage and backpressure in low health hazard, fire protection applications. Featuring a metered bypass system, the 350ADAOSYPIFG efficiently detects leaks and any unauthorized water use. Its single access cover reduces downtime and added costs associated with maintenance and repairs. Lighter in weight than the 350DA Model, the 350ADAOSYPIFG features a short lay-length for compact, versatile installation in horizontal or vertical positions.
