A1-B Backflow Spec sheets.pdf

This document is a product specification submittal containing technical data sheets and specification sheets for reduced pressure principle assemblies and related backflow prevention devices used in potable water systems.

The file includes detailed specifications for multiple backflow prevention assembly models from manufacturers including ZURN, Wilkins, FEBCO, and Watts. Key products specified are: Model 375XL and 375XLH reduced pressure principle assemblies (sizes 1/2" to 2"); Model 975XL and 975 reduced pressure principle assemblies (sizes 3/4" to 2"); FEBCO Model 825Y/LF825Y/825YR reduced pressure backflow preventers (sizes 3/4" to 2"); Watts Model 909 series reduced pressure zone assemblies (sizes 2 1/2" to 10"); Watts Series LF709 lead-free double check valve assemblies (sizes 2 1/2" to 10"); and Watts Model 765-QT-PVB 2 vacuum breaker (2 inch). All assemblies are designed for installation on potable water lines to protect against backsiphonage and backpressure of contaminated water. All products comply with ASSE Standard 1013, AWWA standards (C511, C550, C511-92), NSF/ANSI/CAN standards, CSA certification, UL classification, and Foundation for Cross Connection Control and Hydraulic Research approvals. Maximum working pressures range from 150 to 175 PSI with temperature ratings from 140°F to 180°F. Materials include ductile iron, cast bronze, stainless steel, and FDA-approved components. The specifications provide detailed dimensions, weights, flow capacity curves, material compositions, and installation requirements for each model.
