Product Details

Zurn Industries 4-375L

The 375 Reduced Pressure Principle Backflow Assembly is utilized where a potential high health hazard exists and is ideal for use when lead-free valves are required protecting against both backsiphonage 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. With multiple options for NRS, OS&Y, and Butterfly shut-off valves, the 375 utilizes the Zurn Wilkins low headloss Compound Check and offers the lowest lifecycle costs on the market.
