Bell & Gossett 101231LF Check-Trol Isolation Flow Control Flange Lead-Free 3/4" NPT x Flange

Check-Trol is the solution for circulator installations. Installing a Check-Trol on the discharge of the circulator gives you the features of a Flow Control Valve, Isolation Valve and Companion Flange. Another advantage of the Check-Trol is the minimal pressure drop, especially when compared to the losses that can be experienced when a check valve is installed internal to the circulator. The Check-Trol flanges are packaged with an isolation flange of the same size to create a pair. Capscrews and nuts are included. Features and Benefits • Combines three valves in one: Isolation Valve, Check Valve and Companion Flange • Free floating flange allows easy alignment and installation of pumps • Prevents gravity circulation • Isolates the circulator so you don’t need to drain the entire system • 50 state Lead Free
