PROBLEM TO BE SOLVED: To provide an excellent high pressure fluid control valve hardly receiving wear, capable of substantially ignoring a leakage of an internal operation fluid and contributing to a long life of the fluid control valve and a reduction of operation cost and maintenance cost. SOLUTION: The high pressure fluid control valve for operating a fluid operation device is disclosed. In order to substantially minimize a sound speed stream damage to an actual sealing surface of a valve seat, it is preferable that a restricted flow area is provided at an upstream side of the ball/poppet substantially line-contacted with the truncated conical valve seat. It is preferable that the ball/poppet can be radially floated in a poppet guide and is substantially automatically aligned to the valve seat. It is preferable not to generate a cross- over leakage by closing a discharge ball/poppet immediately before a feed ball/poppet is opened.
