Abstract: A metering valve assembly for accurately controlling the flow of fluid independent of the pressure fluctuations at the input or at the output of the metering valve assembly. An electrical coil mounted on the assembly housing controls the position of an armature of an electromagnet in a permanent magnet field which, in conjunction with a nozzle assembly transmits pressure through suitable conduits to control a first slider valve. The displacement of the first slider valve controls the opening of a port area so that the flow through the port area is a function of the differential pressure developed across the port area with the output of the port directed through suitable conduit means to a second slider in the valve which is opposed to the upstream pressure of the metering valve.
