Taco Comfort Solutions expands its line of boiler-feed valves to provide contractors with a greater number of choices while also improving safety, function and convenience, the company notes. The brass boiler-feed and dual-check backflow preventer with atmospheric vent is available as a combination unit or the boiler-feed valve and backflow preventer each can be purchased separately. 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 simple pressure-setting adjustment between 10 and 25 psi, which is separate from the exclusive, lockable fast-fill lever.
