Taco Flo-Cheks are used in a forced hot water heating system to prevent “gravity”
circulation during periods when the boiler is hot but the space heating zone is not
wanted. This makes it possible for the use of the heating boiler to maintain domestic
hot water year round. In systems with multiple circulator zones, Flo-Cheks allow
heat to flow only into the zones that are calling for heat. Also, the thumb screw
can be manually opened for gravity feed applications if the main circulator stops
operating.
