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, High Performance Butterfly Valve 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.
