Description
–
The integral design of the Taco 3450 Combi Valve combines a cartridge style backflow
preventer with a pressure regulating cartridge style boiler feed valve into a unique
one piece body configuration. Taco’s 3450 combination dual check backflow with
atmospheric vent and boiler feed valve with purge auto-reset, dial in pressure setting
and adjustable indicator sets a new standard for performance and serviceability.
Designed for use in hydronic heating systems the duel check backflow prevents heating system water from flowing back into the supply water piping if the supply pressure falls below the heating system pressure. The boiler feed valve automatically fills or refills (make-up water) the closed heating system to the desired cold fill pressure. Both the backflow and the feed valve contain cartridges that can be serviced or replaced without draining the entire heating system.
