Watts‘ BD1156 dial-set boiler fill valve provides boiler installers and end users a faster, easier and safer way to fill hydronic heating systems. The BD911 is a combination of the BD1156 dial-set boiler fill valve and a backflow preventer. With a simple-to-use pushbutton fast fill, the BD1156 provides a fill rate of 25 gpm, which speeds system startup and saves installers time. A built-in auto-stop feature prevents the fast fill from over-pressurizing the system above 25 psi.
