Hot Water Boiler Flow Control Valve

Boiler Feed, Backflow Preventer & Combination Valves

2020-10-24 · These valves automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve. The dual control combines the boiler feed valve with an in-line pressure relief valve connected at the outlet end. The backflow prevents contamination of the potable water system if supply pressure should fail.
