009-FS

Series 009-FS reduced pressure zone assembly backflow preventers are designed to prevent the reverse flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. They have a bronze body construction (1/4 to 2 inch) or FDA approved epoxy coated cast iron (2 1/2 to 3 inch), two in-line independent check valves, replaceable check seats with an intermediate relief valve, and ball valve test cocks. Series 009-FS is ideal for protection of health hazard cross-connections or for containment at the service line entrance. Check with local water authorities for installation requirements. Maximum working pressure is 175 psi (12.06 bar).

This series features an integrated 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.
