Abstract: PURPOSE:To accurately and speedily changeover pipe passages for flowing fluid of low pressure and a large amount by arranging a partition plate which is rotationally driven around a shaft between openingss of a valve chamber so as to select either a first position where a first opening is closed or a second position where a second opening is closed. CONSTITUTION:When a rotary actuator 38 is rotated according to signals from a controller 42, a driving shaft 27 is rotated through gears 40, 36. One of first and second openings 30, 31 is closed while the other is opened. Namely, when an interruption plate 29 is rotated rightward, the first opening 30 is communicated with a third opening 41, and the second opening 31 is closed. When the plate is rotated leftward, the second opening 31 is communicated with the third opening 41, and the first opening 30 is closed. While the second opening 31 is closed by the interruption plate 29, the plate 29 composes a part of an inner wall of a casing 20. The first opening 30 and the third opening 41 on both ends of the casing 20 is linearly communicated with each other. Fluid resistance is thus lowered. The fluid resistance is also low in the state that the first opening 30 is closed and the second opening 31 is opened.
