Taco 220-6 1" MPT Cast Iron Flo-Chek Valve
$ 53.38Taco 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. Available in 3/4” and 1” bronze sweat in-line design or 3/4” - 2” cast iron universal threaded body design. The Taco MPV can be used for sizes above 2”.
