Description

This 8 inch Lead Free MasterSeries LF880WZ Reduced Pressure Zone Backflow Preventer Assembly provides protection against high hazard (toxic) fluids in industrial water systems. Its robust ductile iron body features ArmorTek epoxy coating for superior corrosion resistance and extended lifespan. Key components like the relief valve seat and check components are stainless steel for maximum performance and durability. This assembly includes domestic NRS shutoffs and an integrated SentryPlus Alert flood sensor for detecting excessive water discharge. Designed for drop-in replacement, it offers a longer gate-to-gate length for competitor Z-pattern valves and supports both N-pattern and Z-pattern installations. Rated for 175 psi max working pressure and 33-140°F.

Installation & Compatibility

  • This MasterSeries LF880WZ Reduced Pressure Zone assembly is designed for drop-in replacement of competitor's valves, featuring a longer gate-to-gate length specifically for Z-pattern orientation.
  • It supports flexible installation in both N-pattern (horizontal) and Z-pattern (vertical up) configurations.
  • End connections are compliant to ASME B16.1 Class 125 and AWWA Class D Flange standards.

Flood Sensor Connectivity

  • An add-on connection kit (sold separately) is required to activate the integrated flood sensor.
  • Connection kit options allow for integration with Building Management Systems (BMS), cellular communication, or the Sensor Control Monitor, enabling alerts to BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
  • Without an add-on connection kit, the flood sensor operates as a passive component and will not communicate alerts.

FAQs

What type of fluid protection does this backflow preventer offer?

This MasterSeries LF880WZ Reduced Pressure Zone assembly is designed to protect against high hazard (toxic) fluids in industrial water services, preventing backpressure and backsiphonage.

What is the purpose of the integrated flood sensor?

The integrated flood sensor with SentryPlus Alert technology detects excessive water discharges from the relief valve, signaling potential flooding events.

Is an additional kit required to activate the flood sensor?

Yes, an add-on connection kit (sold separately) is required to activate the flood sensor and relay alerts via BMS, cellular communication, or a Sensor Control Monitor. Without it, the sensor is passive.

What type of shutoff valves are included with this assembly?

The assembly comes with domestic NRS (Non-Rising Stem) resilient seated gate valves, which comply with AWWA C509 standards.

What material is the valve body made from, and how is it protected?

The valve body is constructed from ductile iron Grade 65-45-12 and features ArmorTek® powder coating applied to both internal and external surfaces for advanced corrosion resistance.
