Connections

  • This assembly is designed for horizontal flow orientation.
  • End connections are compliant to ASME B16.1 Class 125 and AWWA Class D Flange standards.

Flood Sensor Activation

To activate the integrated SentryPlus Alert® flood sensor for relaying alerts about excessive water discharge, an add-on connection kit is required. This kit enables communication with Building Management Systems (BMS), cellular networks, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Additional Details

This 10 inch lead free MasterSeries® LF860 Reduced Pressure Zone assembly is engineered to protect potable drinking water systems from backpressure and backsiphonage conditions in high hazard/toxic applications. It includes UL Classified and FM Approved outside stem and yoke (OSY) shutoff valves, a lead free ductile iron body, top mounted test cocks, spring-loaded check valves, and a pressure differential relief valve.

Advanced Corrosion Protection

  • The assembly's iron components are coated with ArmorTek®, a patented three-part advanced epoxy system designed to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate.
  • Improved with a stainless steel relief valve seat and stainless steel check components, these rugged assemblies offer enhanced dependability and extended valve life.

Flood Detection and Alerts

  • Features a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • An add-on connection kit is required to activate the flood sensor for alert relay. Kit options include BMS, cellular communication, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

FAQs

What is the primary function of this backflow preventer?

This backflow preventer is designed to protect potable water systems from backpressure and backsiphonage conditions in high hazard/toxic applications, ensuring water quality and safety.

Does this assembly comply with lead-free requirements?

Yes, the wetted surface of this product contains less than 0.25% of lead by weight, fully complying with low lead installation requirements for potable water systems.

How does the ArmorTek® coating benefit the assembly?

The patented three-part advanced epoxy ArmorTek® coating system is applied to the iron components to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate, thereby extending the assembly's lifespan and performance.

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

The SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate the sensor and relay alerts for potential flooding events, an add-on connection kit (e.g., BMS, cellular, or Sensor Control Monitor) is required.

What are the key material components of this assembly?

The assembly features a durable ductile iron main valve body and relief valve body, complemented by stainless steel check seats, a stainless steel relief valve seat, disc holders, and springs for maximum performance and durability.
