| A new bulletin that describes the benefits of isolation
flanges has been published by Bell & Gossett. The bulletin (A-117A)
explains the isolation flange’s specifications and operating data, which include
maximum working pressure and maximum operating temperature, as well as installation
suggestions. Also identified are the numerous benefits of the product such as easy service
and replacement of the circulator without the need to drain the system. The bulletin
highlights B&G's free-floating design that allows the flange to rotate, eliminating
the need to align the bolt holes of the flanges when installing to the system piping.
An informative 4-color chart allows engineers and contractors to review the various
sizes and materials that are available. Available in 3/4", 1" and 1-1/4"
NPT and sweat connections, the flanges allow easy installation, service and replacement of
the circulator. The isolation flanges may 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 flanges described in the bulletin utilize 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 and potable water systems.
