Watts LF909M1-OSY-S-FDA-FS 10 - Part of the LF909 Large Series
This 10 inch lead free reduced pressure zone backflow preventer assembly prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards. This assembly consists of an epoxy coated cast iron body, outside stem and yoke resilient seated gate valves, a strainer, captured spring check valves, replaceable seats, top mounted test cocks, and a field reversible pressure differential relief valve. 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. This backflow assembly contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor relays a signal that triggers notification of potential flooding to service personnel. The add-on sensor connection kit is available for building management systems and cellular communication.
Features- Features a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve
- Alert features available with add-on sensor connection kit
- Utilizes advanced ArmorTek coating technology to resist corrosion of internals
- Cast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion
- Unique patented air-in and water-out design provides high capacity relief valve discharge performance during emergency conditions
- Outside stem and yoke gate valves
