Fuel Metering Valve (FMVA)

Fuel Metering Valve

Fuel Metering Valve Assembly (FMVA) incorporates an electro-hydraulic, 4-way fuel-metering servo, a pressure compensating by-pass valve, pilot operated solenoid and shut-off valve into a single integrated package. The FMVA uses a first-stage, electro-hydraulic servo. This servo is based on the 3-way, clevis-type fuel metering servo that is currently used in a variety of applications such as direct metered flow and pressure compensated flow control for turbine engine fuel systems and actuator position control.
