Lead Free* Double Check Valve Assemblies, Cast Iron - LF709

3.5(11 reviews)

Series LF709 Lead Free* double check valve assembly backflow preventers help stop the reverse flow of polluted water from entering into the potable water supply. This series has a modular check design for easy maintenance and is ideal at referenced cross-connections identified in non-health hazard applications. The series features Lead Free* construction to comply with Lead Free* installation requirements. Maximum working pressure is 175 psi (12.06 bar).

The coating on this backflow assembly uses ArmorTek^®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.

The IOT model features sensor technology integrated on test cocks to measure pressure fluctuations at three points. Pressure measurements allow assessment of the performance of the backflow preventer assembly. An add-on monitoring connection kit is required to collect, convert, and transmit data values to a building management system.

Features
