For Preventing Gravity Flow in Forced Hot Water Systems and to Permit Summer-Winter Operation of Indirect Water Heaters, Use Bell & Gossett Flo-Control Valves.

For greater installing convenience, B&G Flo-Control Valves in 3/4"-1 "-1 -1 /4" 1-1/2"-2" sizes are made in combination straight-angle patterns. These sizes can be installed in either horizontal or vertical pipe lines, giving the installer wider latitude in meeting various piping problems. Larger sizes are made in conventional straight and angle patterns.
