Isolation Flanges - NPT and Sweat Connections

The isolation flange is a combination of a full port isolation ball valve and a companion flange for circulators. The isolation flange allows easy service or replacement of the circulator without the need to drain the system. Free-floating flanges eliminate the need to align flanges making the pump installation a snap. Includes capscrews and nuts. Can be used with most circulators, including NRF/NBF/SSF wet rotors, Series PL’s, Series 100, HV, PR & LR and other manufacturers’ pumps. Available Sizes: 3/4", 1" & 1-1/4" (refer to dimension and weight table for details).

When closed, the isolation flanges isolate the circulator from the rest of the system so the system does not need to be drained when removing the circulator.
