Zurn Industries 6-350ASTBG

The 6'' 350ASTBG Double Check Backflow Assembly, with grooved end butterfly valves with integral supervisory switches, protects against back siphonage and backpressure in low health hazard applications. The use of our Patented Compound Check guarantees reliable performance and improved flow characteristics, making installation ideal for lower-pressure systems. Its 304L grade stainless steel valve body and access covers are corrosion-resistant for lower lifetime maintenance costs. Its lightweight design and short lay-length also ensures easy, compact installation.
