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
- Water or water/glycol media
