Claim 10:
11. A method, comprising:
actively adjusting a preload member of a valve using an actuator operatively connected to move the preload member while fluid is supplied to the valve; and
supplying fluid to the valve via a pump, wherein actively adjusting includes moving the actuator to adjust the preload member of the valve without shutting down the pump, wherein the valve is disposed in a fluid line fluidly connecting a fluid source to a fluid destination therebetween, wherein adjusting the preload member is performed while the fluid is supplied to the 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, wherein the pump is configured to pump fuel from the fuel tank to the one or more fuel nozzles, wherein the 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.
