• Combines 3-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

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. The ball valve allows the circulator to be removed from the system without draining the system. The internal spring check prevents gravity circulation. Free floating companion flange makes pump installation a snap. 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.
