Watts 994-OSY-FS 10 - Part of the 994 Series
This 10 inch lead free reduced pressure zone assembly backflow preventer help stop the reverse flow of liquids due to backpressure or backsiphonage, where potential health hazard exists. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. This assembly consists of a short lay length stainless steel body, test cocks, corrosive resistant stainless steel bottom mounted relief valve, torsion spring check valves, and resilient seated gate valves with non-rising stem. 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 body
- UL and FM outside stem and yoke resilient seated gate valves
- Health hazard application
- No special tools required for servicing
- 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
