leverisolationdrain

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 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.
