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.

In systems with multiple circulator zones to allow heat to flow only into the zones that are calling for heat
• 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

The Hydrotrol (HT) flow control valve is used to prevent overheating of zones due to gravity flow in hydronic heating systems and will permit summer-winter operation of indirect water heater. The HT valve allows fluid to pass when the system or zone pumps start. When the system or zone pumps are not operating, the HT valve remains closed, preventing gravity circulation. The HT valves are designed with a 1/2 turn knob that can be manually opened when draining the system or for bypass purposes. The HT valve can be installed in either the horizontal or vertical orientation.

Prevents rooms (zones) from overheating due to gravity circulation
• Elastomer seal provides positive, shut-off eliminating the need for an isolation valve
• Brass body and non-ferrous internals
• Straight angle configuration allows for quick and easy installation
• Vertical design option saves installation time and material
• Turn knob for system draining or valve bypass
• Compact, lightweight design
