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.

Features

• Utilizes advanced ArmorTek coating technology to resist corrosion of internals
• The valve body shall utilize a coating system with built in electrochemical corrosion inhibitor and microbial inhibitor
• Prevents the backflow of pollutants that are objectionable (non-toxic) from entering into the potable water supply
• Primarily used on potable drinking water systems where code mandates protection from backpressure and backsiphonage conditions
• Winterization feature with disc retainers and valve body drain ports
• Inline serviceable assembly requires no special tools
