Overview Details for 3450-2

1/2" Combination Boiler Feed Valve & Backflow (NPT x Sweat)

The integral design of the Taco 3450 Combi Valve combines a cartridge style backflowpreventer with a pressure regulating cartridge style boiler feed valve into a uniqueone piece body configuration. Taco’s 3450 combination dual check backflow withatmospheric vent and boiler feed valve with purge auto-reset, dial in pressure settingand adjustable indicator sets a new standard for performance and serviceability.

Designed for use in hydronic heating systems the duelcheck backflow prevents heating system water from flowing back into thesupply water piping if the supply pressure falls below the heating systempressure. The boiler feed valve automatically fills or refills (make-up water)the closed heating system to the desired cold fill pressure. Both the backflowand the feed valve contain cartridges that can be serviced or replacedwithout draining the entire heating system.
