This patent describes a metering valve for supplying fuel to a turbine engine in response to an operational signal, the metering valve comprising: a housing having a cavity therein with an inlet port, a control port, and an outlet port, the inlet port being separated from the outlet port by a first annular seat. The first annular seat is connected to the outlet port by an outlet conduit, the control port being connected to the outlet conduit by a by pass conduit; wall means for separating the cavity into first, second and third chambers. The first chamber is connected to the inlet port for receiving fuel having a fluid pressure P/sub 1/, the second chamber is connected to the outlet conduit, the third chamber is connected to the first chamber and the control port; a plunger connected to the wall means having a face therein that moves with respect to the first annular seat to regulate the flow of fuel from the first chamber into the outlet conduit, the fuel in the outlet conduit having a fluid pressure P/sub 2/; and feedback valve means connected to the wall means for controlling the fuel flow from the first chamber to the third chamber.
