To provide a three-way valve where the constraint of the design of an exhaust gas treatment system is hardly added and actuation can be stably operated.SOLUTION: In a three-way valve 10 where an inflow passage 31 and a first outflow passage 32 are formed in a direction perpendicular to the mutually opposed direction and a second outflow passage 33 is formed in a direction orthogonal to an opposing direction, a valve body having a valve body inner flow passage 40 switchable from a state that the second outflow passage 33 is closed and the inflow passage 31 and the first outflow passage 32 are communicated to a state that the first outflow passage 32 is closed and the inflow passage 31 and the second outflow passage 33 are communicated, is provided; and an inert gas introduction port 50 formed with an introduction port 50a introducing an inert gas into a valve chamber 36 at a side opposing the second outflow passage 33, is provided.SELECTED DRAWING: Figure 1 【課題】 排ガス処理システムの設計に制約を与えにくく、安定的に作動できる三方弁を提供する。【解決手段】 相互に対向する方向に流入路３１と第１流出路３２が形成され、該対向方向に直交する方向に第２流出路３３が形成された三方弁１０であって、第２流出路３３を閉鎖し、流入路３１と第１流出路３２を連通させた状態と、第１流出路３２を閉鎖し、流入路３１と第２流出路３３を連通させた状態とに切り換え可能な弁体内流路４０を有する弁体を備え、第２流出路３３と対向する側に、弁室３６内に不活性ガスを導入する導入口５０ａを形成した不活性ガス導入ポート５０を備えている。【選択図】 図１
