Bell & Gossett has introduced a new line of Isolation Flanges (patent pending) that combines a full port isolation ball valve and a circulator flange to allow circulators to be isolated from the rest of the system for quick and easy removal. This feature eliminates the need to drain the entire system when removing the circulator for service or replacement. Free-floating flanges rotate to eliminate the need to align the bolt holes of the flanges when installing it to the system piping. Available in 3/4", 1" and 1-1/4" NPT and sweat, the flanges are designed to be used with all brands of circulators, including Bell & Gossett's NRF, NBF, and SSF wet rotors, Series PL, Series 100, HV, PR and LR circulators. The isolation flange utilizes a standard 90-degree-turn ball valve and long handle for ease of operation. The non-ferrous wetted internal components make the isolation flanges ideal for hydronic heating systems. Bell & Gossett.
