1/2 In Bronze Combination Dial Set Fill Valve and Backflow Preventer, Union Solder or Threaded Inlet x Union Threaded Outlet Connections
This 1/2 inch bronze combination dial set fill valve and backflow preventer is for use in commercial and residential hydronic heating systems to provide make-up water to the boiler, and prevent backflow when supply pressure falls below system pressure. It consists of a bronze model 9D backflow preventer and a bronze model BD1156F feed water pressure regulator in one pre-assembled unit. The high capacity fill valve provides quick system filling and purging. It is designed for use in the boiler feed lines of hydronic heating systems.
