Description
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.

Flow Control Valve
Prevents gravity circulation and flow in the wrong direction.

Isolation Valve
Allows for servicing or replacement of the circulator without draining the system.

Companion Flange
Free-floating companion flanges allow easy alignment for optimal handle positioning.

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.
