The Proportional Fuel Control Valve is comprised of three primary components, the Servoid -Driver, a Proportional Metering Valve and the Delta-P Regulator.

The Servoid Driver, is a current-driven, proportional DC solenoid which responds to either analog or digital (1 kHz pulse width modulated) signals. Input current (0 to 500 mA) is translated into a specific displacement with infinite resolution. The displacement is applied to a precision metering poppet with resulting flow control. Servoid drivers also include suspended armature construction with no sliding elements. This provides low hysteresis and long component life.
The Proportional Metering Valve is a proprietary, configuration providing extremely high flow capacity in a single stage.
The Delta-P Regulator is a pressure reducing, differential pressure regulator that maintains a constant pressure differential across the metering orifice. This pressure differential insures a constant net flow even while supply and downstream pressures vary, as is common with turbine engines. This valve and a corresponding air metering valve control the flow and ratio of air & fuel to airborne turbine auxiliary power units. These systems include complex feedback to account for a wide range of startup parameters. Servoid valves also function well in under open-loop conditions with high repeatability. This valve can be used anywhere highly repeatable flow control of liquid media is a requirement and similar valves are also available for control of gases such as air, nitrogen, and hydrogen.
