Claim 0:
1. A system comprising:
a moveable component configured to move between one or more positions;
a biasing member operatively connected on a first side to bias the moveable component to a respective one of the one or more positions;
a preload member operatively connected to provide a force to a second side of the biasing member;
an actuator operatively connected to move the preload member in response to a signal from a controller to adjust the force applied to the second side of the biasing member and to adjust displacement of the moveable component, wherein the moveable component includes a valve body disposed in a valve chamber and wherein the biasing member and preload member are disposed in the valve chamber to form a flow valve, and further comprising a fluid line fluidly connecting a fluid source to a fluid destination, the flow valve disposed in the fluid line between the fluid source and the fluid destination, wherein the controller is configured to control the actuator to adjust the preload member while the fluid is supplied to the flow valve in the fluid line, wherein the fluid source is a fuel tank and the fluid destination is one or more fuel nozzles, wherein the fluid line is a fuel line fluidly connecting the fuel tank to the one or more fuel nozzles, further comprising a fuel pump configured to pump fuel from the fuel tank to the one or more fuel nozzles, wherein the flow valve is one of a pressure regulating valve, a flow divider valve, or a fuel nozzle valve and wherein the controller is configured to actively control the actuator to adjust the preload member of the valve in the fuel line to compensate for load changes in the fuel line.
