Taco Universal Flo-Checks are designed for use in hot water heating systems to prevent gravity circulation when the boiler is operating, but the space heating zone is not wanted. Taco Flo-Check allows to use the heating boiler for domestic hot water throughout the whole year. 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 appplications if the main circulator stops operating.

 

Features:

Maximum Operating Pressure: 125 PSI (862 kPa)
Maximum Operating Temperature: 277°F (136°C)
Media: Water or Water + Glycol

If you look at the main product picture, you will see the arrow pointing the direction of the flow. When water flows in the direction of the arrow, it will be unobstructed. When there's backflow or no flow in the system, the valve will block this flow.
