Taco flo-checks have dependably stopped gravity circulation in forced hot water heating systems for over 40 years. Flo-checks 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-checks 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-checks open automatically when the circulator starts running

Taco B146-20

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

Resideo Braukmann DS06 Dial Set Pressure Regulating Valve is a high quality pressure regulating valve that maintains a constant outlet pressure over a wide range of inlet supply pressures. It is suitable for potable water and irrigation applications. The downstream pressure adjustment dial eliminates the need for a pressure gauge when adjusting the pressure setting (static pressure only).

Built-In Dial-Set- no gauge is needed to install or set static pressure
• Built-in strainer to simplify maintenance
• Fabric reinforced diaphragm regulator, stainless steel and engineered thermoplastics internal parts
• Balanced single seat construction
• Minimum pressure differential between inlet and outlet ports is 14.5 psig
• Plus or minus 4 psig dial calibration
• Less than 0.25% of weighted average of low lead content
• 1/4" NPT gauge tap
• 10:1 maximum reduction ratio
• Double union sweat union fittings
