Description

This 3 inch lead-free reduced pressure zone backflow preventer assembly protects potable water supplies from pollution due to backsiphonage or backpressure. Its durable cast iron body features advanced ArmorTek coating for superior resistance to corrosion, including microbial induced corrosion (MIC). An integrated SentryPlus Alert flood sensor detects excessive water discharges from the relief valve, providing early warning when activated with an optional connection kit. This compact, modular unit with NPT connections is ideal for health hazard cross-connections and continuous pressure piping applications. Item F122650.

Additional Details

This 3 inch lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering into the potable water supply due to backsiphonage and/or backpressure.

It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and for contaminants at the service line entrance.

Features

  • Features a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve.
  • Alert features are available when activated with an add-on sensor connection kit, compatible with Building Management Systems (BMS) and cellular communication.
  • Utilizes advanced ArmorTek coating technology to resist corrosion of internals.
  • Cast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
  • Compact, space saving design.
  • No special tools required for servicing.
  • Single access cover and modular check construction for ease of maintenance.
  • Top entry to all internals for immediate accessibility.
  • Captured springs for safe maintenance.
  • Internal relief valve for reduced installation clearances.
  • Replaceable seats for economical repair.

Note: An add-on connection kit is required to activate the flood sensor. Without the connection kit, the sensor is a passive component that has no communication with any other device.

FAQs

What is the primary function of this backflow preventer?

This reduced pressure zone backflow preventer is designed to prevent polluted water from flowing back into the potable water supply due to backsiphonage or backpressure, safeguarding drinking water in continuous pressure piping applications.

What material is the body made from?

The body is constructed from lead-free cast iron and features ArmorTek®, a patented three-part advanced epoxy coating system that protects against microbial-induced corrosion (MIC) and exposed metal substrate.

Does this model include shutoff valves?

No, this specific LF009-LF model is supplied without shutoff valves. It is designed for installations where separate shutoff valves are provided or not required.

How does the integrated flood sensor work?

The integrated flood sensor with SentryPlus Alert technology detects excessive water discharges from the relief valve. To activate its alert features for notification, an add-on sensor connection kit (sold separately) is required, which can communicate with BMS or cellular systems.

What are the maximum operating pressure and temperature ratings?

For 2 1/2 inch to 3 inch models, the maximum supply pressure is 175 psi (12.1 bar). The water temperature can be 110°F (43°C) continuous or 140°F (60°C) intermittent.
