Prevent siphonage and back pressure:The 3/4" Reduced Pressure Zone (RPZ) Assembly effectively prevents siphonage and backpressure.
Compact design: This RPZ valve is constructed from high-quality bronze, easy to maintain, and allows in-line service with just one access cover. Ideal for protection in continuous pressure piping applications.
Operation: If both check valves of the RPZ assembly fail, the relief valve will open to discharge, preventing fluid from flowing back into the clean supply.
Superior Safety: One of the safest backflow preventers, featuring two independent check valves, a differential pressure relief valve between them, and four test cocks for field testing.
After-Sales Service:Every product undergoes rigorous testing. Should you encounter any issues during use, we will provide you with a satisfactory solution.
