摘要： A steam valve 10 of an embodiment includes: a valve element 32 of a steam control valve 30, the valve element 32 being provided to be movable in an up and down direction; a valve element 42 of a main stop valve 40, the valve element 42 being provided under the valve element 32 coaxially with the valve element 32 to be movable in the up and down direction; a valve seat 60 with which the valve element 32 and the valve element 42 come into and out of contact; and a guide tube 43 slidably supporting a valve rod 41 including the valve element 42, and having a flange portion 43a at a bottom side in a casing 20. The steam valve 10 further includes: the casing 20 housing the valve element 32, the valve element 42, the valve seat 60, and the guide tube 43; a drain discharge hole 23 formed at a bottom side of the casing 20; a drain pipe 70 provided with a shutoff valve 71 and communicating with the drain discharge hole 23; and a flow direction changing part 80 which changes a direction in which steam having passed between the valve element 32 and the valve seat 60 and flowing along the guide tube 43 flows toward the drain discharge hole 23.
