ABSTRACT:
A valve apparatus includes a valve shaft, a body, a bearing housing, a fixing device, and an actuator. The body has a flow path therein, and the flow path has an opening degree that is operated by rotation of the valve shaft. The bearing housing rotatably supports the valve shaft, and the bearing housing has a predetermined attachment portion. The fixing device fixes the bearing housing to the body by fastening the predetermined attachment portion of the bearing housing to an outer surface of the body. The actuator is provided to cover the fixing device from outside, and the actuator is fixed to the body and the bearing housing. The actuator applies a driving force to the valve shaft.
