Abstract
A steam valve having a first inclined surface, which is formed at the distal end portion of a valve rod and in which the outer diameter of the valve rod increases from the distal end toward the base end of the valve rod, and a second inclined surface, which is formed on the inside of a portion of a main valve that is positioned on the base-end side of the valve rod and which inclines with the same inclination angle as the first inclined surface. In a state in which a slave valve and the main valve are closed the first inclined surface and the second inclined surface are separated from each other, and when the slave valve and the main valve are in a fully open state the first inclined surface and the second inclined surface abut each other.
