<p>PURPOSE: To provide a valve device easy in assembly/disassembly and mutually changeable by providing two valve halves and a mouth integrated with male and female portions symmetric in X-axis and Y-axis in a butterfly valve attachable/detachable without exposing a content in the valve to the external environment. CONSTITUTION: A valve device interposed in a powder line is provided with first container ports 23, 25 to be connected to a conduit of a material to be handled, and the container ports 23, 25 are separable from each other while sealing the powder material inside from the external environment. When the container ports 23, 25 are integratedly coupled with out in a coupled mode, butterfly valve bodies 27, 29 attached to the container ports 23, 25 are pivotably movable as the valves between the container ports 23, 25. Locking members 31, 33 comprising annular rings are arranged on outer circumferences of the container ports 23, 25, and the locking members 31, 33 are provided to close and lock the valve bodies 27, 29 in the closed condition in an uncoupled mode of a device 21.</p> |
