The Flange Concentric Butterfly Valves is designed to
maintain a seal against bi-directional pressure differential to prevent
backflow in systems designed for unidirectional flow. It accomplishes this with
a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat
valve face on the upstream and downstream sides of the valve, valves have threaded inserts at both sides of
the valve body. This allows them to be installed into a system using two sets
of bolts and no nuts. The valve is installed between two flanges using a
separate set of bolts for each flange. This setup permits either side of the
piping system to be disconnected without disturbing the other side.
