Concentric Butterfly Valve

The valve is designed to maintain a seat against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal. 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.
