Bell & Gossett 101233LF

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. The Check-Trol flanges are packed with an isolation flange of the same size to create a pair. Capscrews and nuts are included.
