。 A bellows whose both ends are closed and forms a fluid passage around the holder is installed between a holder attached to one end of the case and a valve arranged at the other end, and a fluid outlet provided on the holder side of the case. In the pressure control valve, the bellows expands and contracts to adjust the valve according to a pressure difference between the valve and a fluid inlet formed by the valve, and the valve is movable with respect to a valve seat holder and the valve seat holder. and the closed end of the bellows is fixed,
1. A pressure control valve comprising a control rod having a plurality of grooves formed on the outer circumferential surface at predetermined intervals along the circumferential direction and tapered in the axial direction.
