Installation & Sensor Connectivity

  • This assembly supports both horizontal N-pattern and vertical up Z-pattern installation to suit various piping configurations.
  • The integrated SentryPlus Alert® flood sensor requires an add-on connection kit to be activated. These kits can enable communication via BMS, cellular networks, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi. Without a connection kit, the sensor remains a passive component.

Additional Details

This 8 inch Lead Free MasterSeries® LF880V Reduced Pressure Zone assembly is designed to protect potable drinking water systems against backpressure and backsiphonage conditions for high hazard (toxic) applications in accordance with Local Governing Water Utility Code.

Key Features

  • Features a SentryPlus Alert® flood sensor to detect excessive water discharges from the relief valve, providing alerts about potential flooding when activated by an add-on connection kit.
  • Ductile iron valve body construction is fused with ArmorTek®, a patented three-part advanced epoxy coating system engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates.
  • Utilizes stainless steel relief valve seat and stainless steel check components for maximum performance and durability.
  • Designed for inline servicing without requiring special tools, with modules accessed through independently top entry covers.
  • Supports both horizontal N-pattern or vertical up Z-pattern installation.
  • Includes domestic non-rising stem (NRS) shutoff valves.
  • The assembly features modular and repairable pressure differential relief valve with captured modular spring assembly, reversible and replaceable discs, and field replaceable seats.

NOTICE: Use of 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 the need to provide proper drainage in the event of a discharge. Watts® is not responsible for the failure of alerts due to connectivity issues, power outages, or improper installation.

FAQs

What is the primary purpose of this backflow preventer?

This backflow preventer is designed to protect potable drinking water systems from contamination due to backpressure and backsiphonage conditions in high hazard/toxic applications, commonly found in industrial installations.

What does "Lead Free" construction mean for this product?

“Lead Free” indicates that the wetted surfaces of this product, which come into contact with consumable water, contain less than 0.25% of lead by weight, complying with low lead installation requirements.

How does the integrated flood sensor function?

The SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. When activated with an add-on connection kit, it can relay signals to trigger multichannel alerts (call, email, text) to notify personnel of potential flooding.

What type of shutoff valves are included with this assembly?

This assembly includes domestic non-rising stem (NRS) resilient wedge gate valves, which comply with AWWA C509 standards.

What are the maximum operating pressure and temperature ratings for this unit?

This backflow preventer has a maximum working pressure of 175 psi (12.1 bar) and a continuous operating temperature range of 33°F to 140°F (0.5°C to 60°C).
