Watts today announced the BD1156 dial set boiler fill valve, which 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 push-button fast fill, the BD1156 provides a fill rate of 25 gpm, which speeds system start-up and saves installers time. A built-in auto-stop feature prevents the fast fill from over-pressurizing the system above 25 psi. Using the BD1156 or BD911 eliminates the need for a pressure gauge downstream. An easy-to-adjust 8- to 21-psi dial is visible from the top or front, offering installation flexibility. A stainless steel strainer protects the valve disc from fouling. Multiple connection options are available.
