The Bell & Gossett 101247LF is a Check-Trol CTFS-1 LEAD-FREE isolation flow control flange. It integrates three functionalities in one device: an isolation valve, a flow control valve, and a companion flange. This versatility allows for easier installation in circulator systems.
The Check-Trol design prevents gravity circulation and allows for service without system drainage.
