Lead Free* MasterSeries In-Line Double Check Valve Assemblies - Large Diameter - LF850 Large

MasterSeries LF850 Lead Free* double check valve assemblies prevent the backflow of pollutants that are objectionable but not toxic, from entering into the potable water supply. This assembly consists of a fused epoxy coated ductile iron body using ArmorTek coating technology for advanced corrosion resistance and NRS resilient wedge gate valves. Optional OSY RW gate valves are available. Maximum working pressure: 175psi (12.1 bar).

The coating on this backflow assembly uses ArmorTek™ technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
