Zurn Industries 6-375OSY

The Zurn Wilkins 375 Reduced Pressure Principle Backflow Preventer provides high hazard protection for all applications. The flanged, epoxy coated ductile iron body is available with multiple shut-off valve options for installation versatility.


The 6'''' 375OSY Reduced Pressure Principle Backflow Assembly, with OS&Y 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 backsiphonage and backpressure of contaminated water into the potable water supply.

The 375 utilizes the Zurn Wilkins low headloss Compound Check and offers the lowest lifecycle costs on the market.
