Watts LF709-NRS-S-FDA-IOT 4 - Part of the LF709 Series
This 4 inch lead free double check valve backflow preventer assembly is designed to prevent the reverse flow of contaminated water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure. Ideal for protection in continuous pressure piping applications and cross-connections identified as non-health hazards. This assembly consists of an fused epoxy coated cast iron body, NRS resilient seated gate valves, FDA epoxy coated strainer, test cocks, and a modular check design for easy maintenance with center stem guide. The captured spring is accessible through a bolted cover plate. This assembly features integrated pressure-sensing test cocks that measure pressure fluctuations at three points when activated with an add-on monitoring connection kit. The kit collects, converts, and transmits the data values for use in a building management system. The coating on this backflow assembly uses ArmorTek®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
Features- Pressure sensors integrated on the backflow preventer to measure pressure fluctuations at three test cock locations when activated
- Add-on kit available for activating sensors and transmitting data values to a building management system
- A solution for monitoring assembly performance between code testing
- Data access to help drive scheduling of maintenance and repair
- 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
- Non-rising stem gate valves
