Taco® 241-4 241 Horizontal Hydronic Flo-Chek Valve, 1 in Nominal, C End Style, 125 psi Pressure, Bronze Body, Domestic
CBPN: 306880
MPN:241-4
DESCRIPTION
Taco®, 241-4, Hydronic Flo-Chek Valve, Horizontal, Series: 241, 1 in Nominal, C End Style, 125 psi Pressure, 277 deg F, Media: Water/Glycol, Automatic Actuator, Bronze Body, 4-1/4 in W x 4-11/16 in H Dimensions, Domestic
Taco Flo-Cheks 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-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. 125 PSI maximum operating pressure (862 kPa) and 277 deg F maximum operating temperature (136 deg C).

Specifications
Item Features
- Flo-cheks open automatically when the circulator starts running
- When the room thermostat is satisfied and the circulator is stopped
- The flo-cheks close immediately, preventing gravity circulation
- Gravity circulation of water is induced by the difference in specific weight or density of the hot water in the vertical supply pipe and the cold water in the vertical return pipe
- The lighter hot supply side water, which naturally wants to rise, is drawn up and around the system by the pulling down effect of the heavier cold water in the vertical return pipe
- The amount of gravity circulation is dependent on the height of the system and the differential between the hot and cold temperatures
- In systems with multiple zones, ghost flow may occur if a Flo-Chek is not installed on each zone
- Ghost flow is induced when a circulator on one zone is running but is still able to bypass water through a zone that is not calling, due to a differential in piping resistance between the two zones
- For multi circulator systems Flo-Cheks allow flow only into zones calling for heat
- Prevents gravity circulation in a forced water heating system
- 277 deg F Max temperature range f
