To provide a selector valve which can achieve power saving, and to provide a selector valve device.SOLUTION: A selector valve 1 may be connected to a rotary driving source M which rotationally drives around a rotation axis A and switch a passage of a fluid. The selector valve 1 includes: supports 21 to 24 having internal spaces 21a to 24a; and rotating bodies 31 to 34 which are housed in the internal spaces 21a to 24a while being rotatable around the rotation axis A and may be connected to the rotary driving source M. The supports 21 to 24 include external ports 21p to 24p which send or receive the fluid. The rotating bodies 31 to 34 include: valve chambers 31a to 34a in which the fluid is stored; and internal ports 31p to 34p communicating with the valve chambers 31a to 34a. The internal ports 31p to 34p are provided at positions which overlap with the external ports 21p to 24p when the rotating bodies 31 to 34 rotate around the rotation axis A relative to the supports 21 to 24 by a predetermined rotation angle so as to be selectively and fluidly connectable with the external ports 21p to 24p.SELECTED DRAWING: Figure 1B 【課題】省力化を図ることができる切替バルブおよび切替バルブ装置を提供することを目的とする。【解決手段】回転軸Ａ周りに回転駆動する回転駆動源Ｍに連結可能であり、流体の流路を切替可能な切替バルブ１である。切替バルブ１は、内部空間２１ａ～２４ａを有する支持体２１～２４と、回転軸Ａ周りに回転可能な状態で内部空間２１ａ～２４ａに収容され、回転駆動源Ｍに連結可能な回転体３１～３４とを含む。支持体２１～２４は、流体を送出するか、または受容する外部ポート２１ｐ～２４ｐを備える。回転体３１～３４は、流体を収容する弁室３１ａ～３４ａと、弁室３１ａ～３４ａと連通する内部ポート３１ｐ～３４ｐとを備える。内部ポート３１ｐ～３４ｐは、外部ポート２１ｐ～２４ｐと選択的に流体接続可能であるように、回転体３１～３４が支持体２１～２４に対して回転軸Ａ周りに所定の回転角度で回転したときに、外部ポート２１ｐ～２４ｐと重なる位置に設けられる。【選択図】図１Ｂ
