Installation & Monitoring

  • This double check valve assembly is installed at cross-connections to prevent backflow of polluted water into the potable supply, specifically where local inspection authorities identify non-health hazards.
  • The integrated pressure sensors in the IoT test cocks require an add-on monitoring connection kit to collect and transmit data to a Building Management System (BMS) or Building Automation System (BAS) via a wired serial (RS-485) interface.
  • The add-on connection kit and pressure sensors are also available for existing installations.

Additional Details

The Watts LF007 Double Check Valve assembly is a 3 inch lead free device designed to prevent the backflow of polluted water into the potable water supply due to backsiphonage or backpressure, suitable for non-health hazard cross-connections.

This assembly features a compact, modular design with pressure-sensing IoT test cocks and a corrosion-resistant ArmorTek coating.

Key Features

  • Modular, compact design facilitates maintenance and assembly by retaining the spring load.
  • ArmorTek coating technology resists corrosion of internals.
  • Fused epoxy coated cast iron body for durability.
  • Top-mounted Lead Free ball valve test cocks.
  • Sensors integrated at test cocks (No. 2, No. 3, and No. 4) measure pressure fluctuations; activated with an add-on monitoring connection kit (BMS/BAS only).
  • Replaceable seats and seat discs for extended service life.
  • Easier maintenance through a single, top-entry cover.
  • No special tools required for servicing.
  • Low pressure drop.

FAQs

What is the primary function of the Watts LF007 Double Check Valve assembly?

The primary function is to prevent the backflow of polluted water into the potable water supply, specifically at cross-connections identified as non-health hazards. It protects against both backsiphonage and backpressure conditions.

Does this assembly include a coating for corrosion resistance?

Yes, the assembly features ArmorTek® coating technology, a patented three-part advanced epoxy system, applied to the fused epoxy coated cast iron body to resist microbial-induced corrosion (MIC) and protect exposed metal substrate.

What does "pressure-sensing IoT test cocks" mean, and how are they used?

The LF007 assembly includes integrated pressure sensors at test cocks No. 2, 3, and 4 to measure pressure fluctuations. These sensors are activated and transmit data when connected to an add-on monitoring kit, allowing for performance assessment via a Building Management System (BMS) or Building Automation System (BAS).

Is special tooling required for maintenance of the LF007 assembly?

No, the Watts LF007 assembly is designed for easy maintenance through a single, top-entry cover, and no special tools are required for servicing. This simplifies routine checks and repairs.

What is the maximum operating pressure for this backflow preventer?

The maximum working pressure for the Watts LF007 Double Check Valve assembly is 175 psi (12.1 bar).
