Zusammenfassung:	PURPOSE:To improve the abrasion resistance and the burning resistance at the sliding section by forming a ceramic film at least onto the sliding face of valve rod and valve body in steam regulation valve. CONSTITUTION:A steam inlet 2, a steam flow path 6 and a steam outlet 2 are arranged in a valve chamber 1 to open/close the steam path 6 by means of three valve bodies 5. The valve body 5 is supported by a valve support 7 which is supported by a valve rod 4. The valve body 4 is moved up and down in a sleeve 9 by means of a drive mechanism 8 thus to open/close the valve. When applying ceramic coating onto the sliding section of the valve rod 54 and the valve body 5 or the section shown by A, a steam regulation valve having excellent abrasion resistance and burning resistance can be obtained.
