A steam valve control device comprising a solenoid valve that supplies hydraulic pressure to a valve and rapidly releases the hydraulic pressure to a drain when the steam valve is suddenly closed. A steam valve control device characterized by being provided with a buffer mechanism that limits the amount of oil that flows. (2) The buffer mechanism is constructed by changing the shape of the port of the solenoid valve connected to the disk dump valve so that the flow rate is small at the initial stage when the solenoid valve returns. Steam valve control device as described. (3) The steam valve control device according to claim 1, wherein the buffer mechanism includes a dumppot mechanism for delaying the return time of the solenoid valve.
