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.

• 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
• 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

Taco air scoop's special design and internal baffles of Taco air scoops slow water velocity to separate the air from solution. Thanks to this design, Taco air scoops efficiently remove air to provide noiseless, air-free hydronic heating, cooling or combination systems. They also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank.

• 1-piece cast iron construction
• Never requires any servicing
• Engineered baffle separates air from water
• Each air scoop has a vent connection on top for the installation of a 1/8" Taco 400-3 or 416-1 Hy-Vent and 1/2" bottom tapping for a diaphragm expansion tank
• The 1-1/2 - 4" air scoops also have an additional top tapping for the connection of a plain steel expansion tank
• Water or water/glycol media
