Aircraft Shutoff Valve Volume Compensators
Brand: Parker Hannifin
Parker Aerospace's shutoff valve/volume compensator is a multi-function hydraulic valve. Its main purpose is to increase aircraft efficiency and provide pedal feedback to the pilot.
Parker Aerospace's shutoff valve/volume compensator (SOV/VC) is a multi-function hydraulic valve that increases aircraft efficiency and provides pedal feedback to the pilot.
The SOV/VC has five valves contained within a single manifold. These valves work together to provide three basic aircraft functions.
The primary function of the valve is to increase overall aircraft efficiency by shutting-off pump flow to downstream hydraulic consumers while those systems are not in use.
The secondary function is to provide force and travel pedal feedback to the pilot by using a volume compensator that reacts to the output pressure and volume of the pilot's master cylinder.
The SOV/VC also has a tertiary function, which is to direct flow to the brakes to stop wheel motion during landing gear retract operations.
Features- Increases aircraft fuel efficiency while providing pedal feedback to the pilot
- Independent volume compensator for each pilot pedal
