Series LF825YA Lead Free* Reduced Pressure Zone assemblies feature a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.
This series prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. Ideal for protection at health hazard cross-connections in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants. Applications also extend to irrigation systems, boiler feed, water lines and other installations requiring maximum protection. Maximum working pressure: 175 psi (12.1 bar).
