Connections

  • The assembly features NPT inlet and outlet connections for straightforward installation into your plumbing system.

Flood Sensor Connectivity

  • To activate the SentryPlus Alert flood sensor's communication features, an add-on sensor connection kit is required. This kit allows the sensor to relay alerts to facility personnel via BMS or cellular communications (kits sold separately).
  • Without the add-on connection kit, the sensor operates as a passive component, detecting water discharge but without external communication.

Additional Details

The Watts Series SS009M3-QT-FS is a 1/2 inch stainless steel reduced pressure zone backflow preventer assembly, designed to prevent the flow of polluted water from entering the potable water supply due to backsiphonage and backpressure. It is suitable for health hazard installations whenever the downstream liquid may damage bronze materials or where it is desirable to eliminate trace elements of lead and copper.

Applications

  • Industrial or plant use
  • Medical/diagnostic equipment
  • Reverse osmosis systems
  • Carbonated beverage machines
  • Breweries/distilleries
  • Paper and pulp industry
  • Chemical plants and aggressive atmospheres

Key Features

  • Investment cast 316 stainless steel body and cover for superior corrosion resistance.
  • Features NPT inlet and outlet connections for straightforward installation.
  • Equipped with quarter-turn full port resilient seated ball valve shutoffs with tee handles.
  • Includes top-mounted vandal-resistant EZ-TC test cocks with covers for accessible testing.
  • Designed with an internal relief valve for reduced space requirements and easier installation.
  • Replaceable check seats and relief valve seats allow for economical repair without special tools.
  • Bolted-on, top entry single access cover simplifies maintenance.
  • Features two in-line independent check valves with captured springs and corrosion resistant internal parts.

Flood Sensor Technology

  • Includes a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve.
  • When activated with an add-on sensor connection kit (sold separately), the flood sensor relays a signal to facility personnel, helping to prevent potential flooding and costly damage.

NOTICE: An add-on connection kit is required to activate the flood sensor for communication with other devices. Without the connection kit, the sensor is a passive component that has no communication with any other device. The flood sensor does not replace the need to comply with all required instructions, codes, and regulations related to installation, operation, and maintenance of this product, including providing proper drainage in the event of a discharge.
