LF870V
Lead Free* MasterSeries N-Pattern Double Check Valve Assembly Backflow Preventers - Large Diameter
MasterSeries LF870V 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® epoxy coating technology for advanced corrosion resistance. Available with NRS or OSY resilient wedge gate valves. Maximum working pressure: 175 psi (12.1 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.
