Description
The Watts 0391009 1” RPZ Backflow Preventer Assembly LF909-QT is a vital protector that helps to stop the backflow of non-potable water into potable water systems. This RPZ assembly features a double-check valve assembly with a second check valve and an independent relief valve. If the pressure decreases below the predetermined level, the pressure relief valve opens and the primary check valve remains closed tightly so as to prevent the backflow. This equipment is mainly utilized in commercial and industrial applications for HVAC like the manufacturing industries.
