PROBLEM TO BE SOLVED: To provide a valve suitable for utilization for high temperature fluid. SOLUTION: The valve 2 is utilized for high temperature fluid, equipped with a tubular valve box 4 containing fluid flow path 48. The valve box 4 is equipped with a tubular cooling jacket 22. The cooling jacket 22 is formed along the entire surface of an inner wall of the valve box 4 and equipped with a cooling route 36 forcing cooling fluid to flow thereinside. The cooling route 36 is formed by combining a plurality of circulation routes extending orthogonally to an axial line of the flow path 48. Preferably, each circulation route takes one end extending orthogonally to the axial line of the flow path 48 as an upstream part and the other end as a downstream part. COPYRIGHT: (C)2010,JPO&INPIT
