Prevent unwanted heat circulation with the Taco® 220-6 Flo-Chek valve. Designed for forced hot water heating systems, it helps keep hot boiler water from circulating through zones that are not calling for heat. The valve opens automatically when the circulator runs and closes when circulation stops. A manual thumb screw allows gravity-feed operation when needed.
