Watts 1/2 B911 (PRESS XTHD) - Part of the 911 SeriesThis 1 2 inch bronze combination 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 backflow preventer, model 9D, and a bronze feed water pressure regulator, model BD1156F, in one pre assembled unit. The high capacity fill valve provides quick system filling and purging.

It is ideal in health hazard continuous pressure applications such as irrigation systems and industrial process water systems where the water enters the equipment at or below its flood rim

Linear openings allow water to pass through while solid bars block leaves and debris from entering and potentially blocking drain pipes

This kit consists of all rubber parts necessary to repair the applicable valve
