Watts LF957RPDA-OSY-CFM-FS 4 - Part of the LF957RPDA Series
This 4 inch lead free reduced pressure detector backflow preventer assembly help stop the reverse flow of liquids due to backpressure or backsiphonage, where potential health hazard exists. Extremely compact and lighter than traditional designs it is approved for horizontal pattern installation. This assembly consists of a stainless steel body with a quick access sleeve, torsion spring check valves, outside stem and yoke resilient seated gate valves, test cocks, corrosive resistant bottom mounted pressure relief valve, and comes furnished with a cubic per minute meter to detect underground leaks and unauthorized water use. 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
- Stainless steel for corrosion resistance
- UL and FM outside stem and yoke resilient seated gate valves
- 150 pound ANSI/AWWA CL D flanged
- Outside screw and yoke shutoffs
- Compact construction for smaller enclosures
- Bottom mounted relief valve reduces clearance requirements when installed against an outside wall
- Torsion spring check valves provides maximum flow at low pressure drop
