Hydraulic Valves-Image

The Aircraft Wheel & Brake Division designs and manufactures hydraulic valves used to control the flow of hydraulic fluid in a variety of aircraft applications. Their products include:

  • Shuttle valves—used to switch between two hydraulic pressure sources
  • Meter valves—used on powered braking systems as boosting control valves
  • Hydraulic fuses—used to prevent leaks from draining the hydraulic reservoir
  • Park brake valves—used to prevent aircraft from rolling when parked, during engine run-up, or during other static conditions

Their park brake valves are typically actuated by a control cable and can include thermal relief and position sensors to indicate valve status.
