に用いるポペツト弁。[Claims for Utility Model Registration] The conical surface 3a of the poppet valve 3 is brought into contact with the sea surface 2a of the port 2 that communicates the high pressure side 4 and the low pressure side 5, and the poppet valve 3 is moved by the high pressure fluid on the high pressure side 4. In a poppet valve used for a pressure control valve that allows fluid from a high pressure side 4 to flow to a low pressure side 5 through a port 2, between the above-mentioned portion 4 on the high pressure side from the seat surface 2a of the port 2 and the conical surface 3a of the poppet valve 3. A poppet valve for use in a pressure control valve is characterized in that a narrow flow section 7 is formed whose opening area gradually decreases toward the seat surface 2a.
