Title: BUTTERFLY VALVE
Abstract:
The body (12) of a butterfly valve (10) has a first channel (24), and a second channel (26) connected so as to intersect the first channel (24). The valve element thereof is positioned in the first channel (24) in the connecting section with the second channel (26), and is capable of adjusting the state of connection between the first channel (24) and the second channel (26) by rotating. The second channel (26) opening end section that opens to the first channel (24) has a cross-section shaped in a manner such that the opening width is smaller in the direction perpendicular to the axial direction of the shaft than in said axial direction.
