Zurn Industries - 4-375

The 4'' 375 Reduced Pressure Principle Backflow Assembly, with flanged end NRS gate valves, is utilized where a potential high health hazard exists and is ideal for use when lead-free valves are required protecting against both back siphonage and backpressure of contaminated water into the potable water supply. The 375 includes an epoxy-coated inside and out ductile iron valve body eliminating exposure to corrosion. The 375 utilizes the Zurn Wilkins low headloss Compound Check and offers the lowest lifecycle costs on the market.
