1 1/4″ Isolation Ball Valve Flange Corrosion-Resistant Brass Armstrong Circulator Pump Parts

Product Description

Armstrong Circulator Isolation Flanges (CIF) are used in pairs to connect circulating pumps in hydronic systems. These devices rapidly isolate a circulator to be serviced, and eliminate the need to drain and refill the entire system. The CIF integrates a 2-bolt flange connection (common to small circulating pumps) with a full-port ball valve. This practical “all-in-one” design reduces the number of plumbing connections and results in a more reliable, economical and easily serviced hydronic system.
