Abstract
An on-off valve of the present invention includes a valve box which includes an inlet flow path of steam and an outlet flow path which communicates with the inlet flow path through a communication bole, a stop valve body which opens or closes the communication hole, and a stop valve support portion, in which the outlet flow path extends in a direction intersecting the opening direction of the communication hole toward a downstream side in a flow direction of the steam, and a minimum wall thickness of the valve box is smaller than a minimum wall thickness of the valve box.
