The BD1156 Dial Set Boiler Fill Valve with its adjustable dial allows contractors to easily select pressure from 8 to 21 psi.
The BD911 is a combination boiler fill valve and backflow preventer in one pre-assembled unit.
These valves from Watts allows a much faster fill rate than competitive devices – about 25 gallons per minute. That's more than twice as fast as comparable fill valves. As a result, contractors can spend less time filling boilers and avoid the nuisance of cleaning up when a boiler is over-pressurized
