A pressure control valve is provided. The pressure control valve includes a sleeve having an inlet port receiving hydraulic fluid and a low-pressure path communicating with a hydraulic tank, a main poppet opening and closing the low-pressure path with respect to the inlet port, a main poppet spring elastically biasing the main poppet in an initial state by pressing the main poppet, a pilot poppet having an orifice flow path to control pressure in the pressure chamber while maintaining a sliding state against a valve seat when pressure that exceeds a predetermined pressure is generated in the pressure chamber to open an internal flow path of the valve seat, and a pilot poppet spring elastically biasing the pilot poppet in an initial state by pressing the pilot poppet to maintain the internal flow path of the valve seat closed. |
