Description
    The Parker Aerospace automatic bleed valve provides automatic detection and bleeding of air in a hydraulic system. This Parker Aerospace proprietary technology offers the advantage of maintenance-free air management similar to air and oil systems while preserving the benefits of a closed system for improved performance. The device is typically mounted directly to the reservoir as a line-replaceable unit and may be controlled through the aircraft’s computing system.

    Automatic air bleed valves can be designed into reservoir manifolds, or can also be remotely located wherever air collects in a system. This would allow existing fleets to benefit from reduced maintenance time and increased hydraulic system performance.

    TYPICAL OPERATION
    The valve can be located at high points in the return line of the hydraulic system where air is known to collect. With 28 VDC applied to the automatic bleed valve, onboard electronics are used to control a leak-free solenoid valve that purges air from the system.

    APPLICATIONS:
    This technology is already qualified for use on the Boeing 787 and Airbus A350 XWB.

    OPTIONAL FEATURES:
    In addition to our existing units, the Parker Aerospace product development team has the skill set and engineering tools to custom design an automatic air bleed valve that will meet your specific application requirements. Please contact us to see how we can engineer a solution for your application.

    The valve can be designed to operate autonomously, making its own decision to purge air from the hydraulic fluid. Alternatively, the valve can be wired to allow control from the aircraft computer, based on flight profile.

    FEATURES AND BENEFITS:
    • Automatic detection and bleeding of air in a closed-hydraulic system for improved performance
    • Proprietary technology offers the advantage of maintenance-free air management of air and oil systems
    • Onboard electronics are used to control a leak-free solenoid valve that purges air from the system
    • Eliminates need for manual reservoir bleed, saving time and hydraulic fluid
