Boiler-feed, backflow-preventer valve

The company’s brass boiler-feed and dual-check backflow preventer with atmospheric vent is available as a combination unit or separate units. Designed for use in hydronic heating systems, the combination unit prevents heating-system water from flowing back into the supply water piping if supply pressure falls below heating-system pressure.  It also offers pressure-setting adjustment between 10 and 25 psi, which is separate from the lockable fast fill lever.
