The present invention is an integrated two-stage low-leak control valve which is used to control pressure or flow in a hydraulic system such as an automatic transmission valve body. The control valve formed of a single assembly. A valve portion and a solenoid portion are located in the single assembly. The solenoid portion is operably connected to the valve portion with two variable orifices contained in the single assembly. A first variable orifice controls the flow of a fluid medium from a supply port in the integrated control valve to a pressure control region of the integrated control valve, and a second variable orifice controls the flow of the fluid medium to an exhaust port in the integrated control valve.
