A self-regulated pressure control valve such as, for example, a self-regulated pressure reducing valve, comprising, as the principal components, a pressure control valve, a pressure regulating unit, a driving unit for driving the pressure regulating unit, a control unit for controlling the operation of the driving unit, and a pressure setting unit for setting a set pressure. The pressure regulating position of the pressure regulating element of the pressure regulating unit is regulated on the basis of the predetermined functional relation between the pressure regulating position of the pressure regulating element and the controlled pressure so that the pressure regulating element is positioned properly to regulate the controlled pressure to the set pressure. The self-regulated pressure control valve is capable of controlling the controlled pressure at a high response speed. |
