The invention relates to a pressure control valve having a control element that includes a valve component and a drive component. The valve component include an orifice that, in a first position, may be closed by the control element, disconnecting a control chamber from a return chamber, such that a control pressure acts on a first control surface of the control element and in a second position, the orifice may be partially opened, so that the control and return chambers are fluidically connected to each other, such that the control pressure in the control chamber acts on a second control surface of the control element.
