**NOTE: See "Selection Guide" document for a description of pump models applicable for this Check-Trol
The Check-Trol flange is a combination isolation valve, flow control valve, and companion flange for circulators. The full port 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.
Flow Control Valve
Prevents gravity circulation and flow in the wrong direction.
Isolation Valve

Great 3 in 1 product. Makes the mechanical setup look clean.
