Zurn Wilkins 10" 350AST Double Check Backflow Preventer

The Zurn Wilkins 350AST is a robust double check valve assembly designed to prevent backflow in potable water systems, ensuring protection against contamination from backpressure and backsiphonage. This 10-inch model features a durable stainless steel body for corrosion resistance, making it ideal for high-flow applications in commercial, industrial, and fire protection systems. Key benefits include easy maintenance with top-access check modules, reducing downtime and labor costs, and compatibility with grooved or flanged connections for versatile installation. It offers superior flow performance with low pressure loss, outperforming similar products like those from Watts or Apollo in terms of head loss at high velocities. Drawbacks may include higher initial cost compared to basic models and the need for periodic testing to comply with regulations. Applications span irrigation, fire sprinklers, and municipal water supplies. Advantages over competitors include modular design for quick repairs, N-pattern configuration for compact spaces, and certifications like UL, FM, and ASSE 1015 for reliability in critical environments. This unit, manufactured in 2019, appears in excellent condition with minimal wear, suitable for immediate deployment.
