Backflow preventer threaded external type BABM 2 inch 149B70005

Backflow preventer – protection of the water supply network

This BABM type backflow preventer, from the BA family, is a reliable solution for protecting plumbing installations from secondary contamination. Its design, based on two check valves and an intermediate chamber, effectively prevents water backflow, protecting the system from potential hazards. The valve also has a drain valve, allowing for ongoing monitoring of its correct operation.

Construction and application

The BABM isolator is designed for horizontal mounting and is used in installations with clean liquids (water). Its solid construction, utilizing brass (body), POM (check valves) and stainless steel, POM and brass (drain valve assembly), guarantees long-lasting and trouble-free operation. This makes it an ideal choice for both professional installers and end-users looking for a reliable solution. This valve effectively separates the supply zone from the drain, creating an air gap in the event of backflow.
