Watts’ BD1156 dial set boiler fill valve provides boiler installers and end users a fast, easy and safe way to fill hydronic heating systems. With a simple-to-use, push-button fast fill, it provides a fill rate of 25 gal. per min. A built-in auto-stop feature prevents the fast fill from over-pressurizing the system more than 25 psi. Using the BD1156 or BD911 eliminates the need for a pressure gauge downstream. An 8- to 21-psi dial is visible from the top or front. A stainless-steel strainer protects the valve disc from fouling. Multiple connection options are available.
