Taco boiler feed valves automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve. The dual control models combine the boiler feed with an in-line pressure relief valve. The built-in check prevents emptying the system if incoming pressure falls. They feature fast fill rates and an exclusive, lockable fast fill lever. Each valve is adjustable from10 to 25 lb/sq-in, has a built-in check to prevent the emptying of the system if incoming pressure fails, and the easy to use fast fill lever is lockable.
