Reduced Pressure Zone Assembly, 1-1/2 Inch, Lead Free, Bronze, QT Shutoff, Y Pattern, Series 825

This 1-1/2 inch lead-free Y pattern reduced pressure zone backflow preventer assembly prevents the reverse flow of high-hazard (toxic) fluids found in the water from entering the potable water supply due to back siphonage and/or back pressure. It is used in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants. It is also used in irrigation systems, boiler feed, water lines, and other installations requiring maximum protection. This assembly consists of a lead-free body, threaded quarter turn ball valves, test cocks, spring loaded Y pattern check valves, and one hydraulically dependent differential relief valve. This backflow assembly contains a flood sensor with SentryPlus Alert^® technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor can send an alert to notify personnel about potential flooding. Add-on sensor connection kits are available for BMS and cellular communications.
