Flex Flange
Brand: Armstrong Fluid Technology
Armstrong Flex Flange is a rotating flange designed to allow maximum installation flexibility regardless of pump flange orientation. Flex Flange units are available with a spring check valve to prevent the heating medium flowing in the wrong direction in the event of gravity circulation.
The Flex Flange 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 and easily-serviced hydronic system.

- 1/4 turn open/close lever-style handle
