Taco flo-cheks have dependably stopped gravity circulation in forced hot water heating systems for over 40 years. Flo-cheks open automatically when the circulator starts running. They feature a thumb screw to manually open the valve and are available in a cast iron universal body and a bronze sweat in-line configuration.
  • Flo-cheks allow heat to flow only into the zones that are calling for heat
  • Thumb screw can be manually opened for gravity feed applications if the main circulator stops operating
  • Taco flo-cheks open automatically when the circulator starts running

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

  • Open automatically when the circulator starts running, when the room thermostat is satisfied and the circulator is stopped, the flo-checks close immediately, preventing gravity circulation
  • Water or glycol media
