Zurn Industries 10-350ASTOSY

The Zurn Wilkins 10'' 350AST Double Check Backflow Preventer with stainless steel body provides low hazard protection with a corrosion resistant and light weight design. Multiple shut-off and end connections are available for installation versatility.


The 10'''' 350ASTOSY Double Check Backflow Assembly, with flanged end OS&Y gate valves, protects against backsiphonage 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.
