Installation Orientation

  • This assembly is designed for N-pattern and Z-pattern vertical up and vertical down installation, as well as horizontal N-pattern and Z-pattern orientations.
  • The longer gate-to-gate length facilitates drop-in replacement for existing competitor's Z-pattern valves.

Flood Sensor Connectivity

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate the sensor for communication and alerts, an add-on connection kit is required. Connection kit options include integration with Building Automation Systems (BAS) via RS-485 Modbus, cellular communication, or the Nexa® platform through Wi-Fi connectivity via the Sensor Control Monitor.

Additional Details

This 8 inch Lead Free MasterSeries reduced pressure zone backflow preventer assembly protects potable water systems from high hazard (toxic) fluids in industrial installations and applications by guarding against backpressure and backsiphonage conditions.

This assembly is engineered to provide a drop-in replacement for competitor's Z-pattern valves, featuring a longer gate-to-gate lay length.

Key Features

  • Lead Free construction complies with low lead installation requirements (wetted surface contains less than 0.25% lead by weight).
  • Ductile iron valve body design with ArmorTek® coating technology on internal and external surfaces to resist electrochemical and microbial-induced corrosion.
  • Equipped with a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When activated with an add-on connection kit, the sensor relays alerts to personnel.
  • Stainless steel relief valve seat and stainless steel check components ensure maximum performance and durability.
  • Features domestic OSY resilient seated gate valves.
  • Inline serviceable assembly requires no special tools.
  • Reversible and replaceable discs with captured modular spring and clapper check assemblies.
  • Field replaceable seats.

An add-on connection kit is required to activate the flood sensor for communication; without it, the flood sensor is a passive component. Watts® is not responsible for alert failures due to connectivity issues, power outages, or improper installation. Always comply with all required installation instructions, codes, and regulations.

FAQs

What is the primary function of this 8 inch reduced pressure zone backflow preventer?

This backflow preventer is designed to protect potable drinking water systems from contamination by high-hazard (toxic) fluids. It prevents backpressure and backsiphonage conditions in industrial installations and applications.

What does "Lead Free" mean for this product?

"Lead Free" signifies that the wetted surface of this product, which contacts consumable water, contains less than 0.25% lead by weight, complying with low lead installation requirements.

How does the flood sensor feature work and what is needed to activate it?

The flood sensor detects excessive water discharges from the relief valve. An add-on connection kit is required to activate the sensor and enable communication for alerts via BMS, cellular, or Wi-Fi through the Sensor Control Monitor. Without the kit, the sensor is passive.

What type of shutoff valves are included with this assembly?

This assembly includes domestic OSY (Outside Stem & Yoke) resilient seated gate valves, which are UL Classified and FM Approved according to AWWA C515 standards.

What are the maximum operating pressure and temperature limits for this backflow preventer?

The maximum working pressure for this assembly is 175 PSI (12.1 bar), and it can operate continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C).
