Discontinued - Replaced By: LF860-FS Large
Lead Free* MasterSeries In-Line Reduced Pressure Zone Assembly Backflow Preventers - Large Diameter
MasterSeries LF860 Lead Free* reduced pressure zone assembly backflow preventers help protect against high hazard (toxic) fluids in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants. Applications expand to irrigation systems, boiler feed, water lines, and other installations requiring maximum protection.
Improved with a stainless-steel relief valve seat, this rugged assembly yields greater dependability and extended valve life. Available with OSY shutoff valves. Maximum working pressure is 175 psi (12.1 bar).
The ductile iron body is fused with ArmorTek™ coating technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
Flood alert feature available with add-on retrofit connection kit, compatible with BMS and cellular communication.
Features
- Utilizes advanced ArmorTek coating technology to build in electrochemical corrosion inhibitor and microbial inhibitor to resist corrosion of internal parts
- Combines the use of a stainless-steel relief valve seat and stainless-steel check components for maximum performance and durability
- Requires no special tools for inline service
- Is highly suitable for potable drinking water systems where code mandates protection from backpressure and backsiphonage conditions
- Protects potable water against cross-connection contamination of high hazard (toxic) fluids in water services
- Sizes 2 1/2 to 10 Inch
