1. A flow valve assembly for achieving a desired flowrate for a gaseous fuel supply, comprising:
a valve body including a fuel flow inlet, a fuel flow outlet, and an orifice coupling fuel flow inlet and outlet;
a valve member including a shaft and a flow control surface positioned on a first end of the shaft and configured to engage the orifice to control the flowrate of the fuel supply;
a linear motion actuator coupled with a second end of the shaft and configured to move the valve member axially relative to the orifice; and
a controller configured to control the linear motion actuator to move the flow control surface to a position to provide for a desired flowrate of the fuel supply, wherein the desired flowrate is a supersonic value.
