Lead Free* Double Check Valve Assemblies - LF007

Series LF007 Lead Free* double check valve assembly backflow preventers include sensors for use with SentryPlus Alert® technology. The small diameter assemblies include a freeze sensor to signal when temperature nears the freezing point. Model IOT large diameter assemblies include sensors to measure pressure fluctuations at three points for monitoring and assessment of performance.

Small diameter, sizes 1/2 to 2 IN, include a freeze sensor for use with SentryPlus Alert® technology to signal facility personnel when temperature nears and reaches the freezing point. Freeze alerts feature available with add-on connection kit for Wi-Fi networks, building management systems (BMS), and irrigation management systems (IMS).

The series is designed to prevent the reverse flow of liquids from backpressure or backsiphonage in a plumbing system where there is a non-health hazard. Compact construction for installation in tight spaces. The single cover, top entry design provides convenient access for maintenance. Replaceable seats and seat discs. No special tools required for servicing.

All large diameter assemblies, sizes 2 1/2 and 3 IN, are enveloped in ArmorTek^®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
