A steam regulator equipped with a main valve that opens and closes a steam flow path and a pilot valve that drives the main valve, wherein the main valve is connected to a valve body and a valve body that drives the valve body. The pilot valve is configured to have a heat dissipation part between the valve body and the drive part for reducing heat transfer from the valve body to the drive part, and the pilot valve is connected to the predetermined signal air pressure output from the pressure reducing valve and the secondary valve of the main valve. A steam regulator characterized in that it is configured to supply and discharge pilot air to and from a main valve depending on the magnitude of the side feedback pressure, and is connected to an air source via a solenoid valve. 2. In a steam regulator equipped with a main valve that opens and closes a steam flow path and a pilot valve that drives the main valve, the main valve is placed between the valve body and the valve body drive section. The pilot valve is configured to have a heat dissipation part for reducing heat transfer from the electro-pneumatic proportional valve to the drive part, and the pilot valve is configured to control the magnitude of the predetermined signal air pressure output from the electro-pneumatic proportional valve and the secondary side feedback pressure of the main valve. The air source is configured to supply and discharge air to and from the main valve, and the pilot valve is equipped with a valve to cut off the supply of air to the main valve when the secondary side pressure of the main valve becomes negative pressure. A steam regulator characterized in that it is equipped with a closing means.
