Overview Details for 221-6

1-1/4" Universal (CI) Taco Flo-Chek

For more than 40 years, designers and installers have used Taco Flo-Cheks in forced hot water heating systems to prevent (gravity circulation 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-Cheks 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.

Features:

Automatically Opens When Circulator Starts Running Cast Iron, Universal Body or Bronze Sweat-In Configuration
125 PSI Maximum Operating Pressure (862 kPa)
277 degrees F Maximum Operating Temperature (136 degrees C)
