    Backflow Preventer Valves, 909QT Series

    Reduced Pressure Zone Backflow Preventers

    Series 909QT: This valve incorporates the (“air-in/water-out”) principle which substantially improves the relief valve discharge performance. (The emergency conditions of combined back siphonage and back pressure with both checks fouled can defeat the effectiveness of a standard RPZ backflow preventers).

     

    Note: Sizes from 3/4" through 2". Supply pressures to 175 PSI. Water temperatures to 140° F

    Features:

    • (2) Quarter-turn, full-port, resilient seated bronze ball valve shutoffs
    • Ball valve test cocks
    • Bronze body construction
    • Modular design, replaceable seats
    • Tight-seating rubber check valve and relief valve assemblies
    • Stainless steel relief valve seats, shafts and flange bolts
    • Available with or without bronze strainer

     

    The 909QT Series come standard with a flood sensor. Sensor activation kit must be purchased if this feature is desired.

     

    Strainer Not Included on QT models: use Watts strainers to permit interchange from QT to QTS style.
