This 2 inch Watts LF007 Series Double Check Valve Backflow Preventer features NPT end connections, suitable for installation into existing NPT threaded piping systems. The assembly includes union connections (prefix "U") for ease of installation and maintenance. For the integrated freeze sensor to actively communicate alerts for low or freezing temperatures, an add-on connection kit (sold separately) is required. This kit enables communication via Wi-Fi networks, Building Management Systems (BMS), or Irrigation Management Systems (IMS).

Additional Details

This 2 inch Watts LF007 Series Lead Free Double Check Valve Backflow Preventer Assembly is designed to prevent the backflow of polluted water from entering 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 non-health hazards.

This assembly features a lead free cast copper silicon alloy body, NPT end connections, and quarter turn ball valve shutoffs. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs and replaceable check discs and seats. The double check valve also includes an integrated freeze sensor for use with SentryPlus Alert® technology, designed to signal facility personnel when the temperature nears and reaches the freezing point. Iron components are protected with ArmorTek® coating technology, which reduces microbial-induced corrosion.

Features

  • Prevents backflow of polluted water into potable water supply.
  • Lead Free* cast copper silicon alloy body construction to comply with installation requirements.
  • Modular, compact design for easy maintenance and assembly, with a single top-entry cover and replaceable seats and seat discs.
  • Integrated freeze sensor with SentryPlus Alert® technology to monitor temperature and alert facility personnel of freezing conditions.
  • Freeze alerts can be activated with an add-on connection kit (sold separately) for Wi-Fi networks, building management systems (BMS), and irrigation management systems (IMS).
  • ArmorTek® coating technology applied to iron components to resist corrosion.
  • Quarter turn ball valve shutoffs and top-mounted Lead Free* ball valve test cocks.

WARNING: The integrated freeze sensor provides alerts about possible freeze events but cannot prevent them; user action is required to prevent damage. An add-on connection kit (sold separately) is required to activate the sensor's monitoring capabilities.

FAQs

What is the primary purpose of the Watts LF007 Double Check Valve Assembly?

The primary purpose is to prevent the backflow of polluted water into the potable water supply, protecting it from contamination due to backsiphonage or backpressure in non-health hazard cross-connections.

What materials are used in the construction of this backflow preventer?

The body is constructed from Lead Free* cast copper silicon alloy. Iron components are protected with ArmorTek® powder coating, and internal check modules feature captured springs and rubber seat discs.

How does the integrated freeze sensor work, and what is needed to activate it?

The freeze sensor uses SentryPlus Alert® technology to monitor temperatures and signal facility personnel about potential freezing conditions. An add-on connection kit, sold separately, is required to activate its monitoring capabilities and enable communication via Wi-Fi, BMS, or IMS.

What are the maximum operating pressure and temperature limits for this assembly?

This assembly has a maximum operating pressure of 175 psi (12.1 bar) and can operate within a temperature range of 33°F to 180°F (0.5°C to 82°C).

Is this double check valve assembly easy to maintain?

Yes, it features a modular, compact design with a single top-entry access cover. This design allows for easy in-line maintenance and the replacement of internal components like seats and seat discs without special tools.
