Claims

[Claims for Utility Model Registration] (1) In a pilot operated pressure control valve which incorporates a pilot seat body inside the valve body and a check poppet fitted on the outer periphery thereof so as to be slidable in the axial direction of the valve body. , a stepped hole is provided in the valve body, and the pilot seat body has a flange formed at one end thereof to engage with the stepped hole, and the seat portion at the other end is elastically pressed to close the valve body. A pilot poppet is incorporated inside the check poppet, and the pilot seat body is slidably inserted into an opening at one end of the check poppet, and the seat at the other end is elastically pressed to close the check poppet. A pressure control valve comprising a slidable relief poppet with a piston poppet incorporated therein. (2) The pilot seat body locks the flange of the pilot seat body in the stepped hole so that the pilot seat body can move within a predetermined range in the axial direction of the valve body and in a direction orthogonal to the axial direction. 2. The pressure control valve according to claim 1, wherein the pressure control valve is configured to do so. (3) The pilot seat body is configured to fit the pilot seat into the stepped hole in such a manner that the pilot seat body restricts movement in the axial direction of the valve body and can move within a predetermined range in a direction orthogonal to the valve body axis. 2. The pressure control valve according to claim 1, wherein the pressure control valve is configured to lock a flange of the body.
