Zurn Industries 8-350ADAPIOSY

The 8'' 350ADAPIOSY Double Check Detector Backflow Assembly, with Post Indicator gate valve and OSandY gate valve, protects against both back siphonage and backpressure in low health hazard, fire protection applications. Featuring a metered bypass system, the 350ADAPIOSY efficiently detects leaks and any unauthorized water use. Its single access cover reduces down time and added costs associated with maintenance and repairs. Lighter in weight than the 350DA Model, the 350ADAPIOSY features a short lay-length for compact, versatile installation in horizontal or vertical positions.
