VALVE, SHUTTLE (P/N 5084-4) - As Removed

The 5084-4 is a three-port shuttle valve for aircraft hydraulic and pneumatic systems. This valve automatically selects between two pressure sources—typically main hydraulic pressure and an emergency accumulator—while blocking crossflow between them. Commonly installed in landing gear brake control assemblies to ensure reliable brake actuation during normal and emergency conditions.

The valve operates passively without external control, directing whichever pressure source is higher to the output port. Installation requires proper system bleeding and leak-checking per aircraft maintenance manual procedures before returning the aircraft to service.

What is the VALVE, SHUTTLE (P/N 5084-4)?

The 5084-4 is a three-port shuttle valve for aircraft hydraulic and pneumatic systems. This valve automatically selects between two pressure sources—typically main hydraulic pressure and an emergency accumulator—while blocking crossflow between them.

What hydraulic fluid type is the 5084-4 compatible with?

Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the VALVE, SHUTTLE against your aircraft maintenance manual for fluid compatibility.

Does the 5084-4 come pressure-tested and certified?

Overhauled and repaired hydraulic components are pressure-tested per manufacturer specifications and include 8130-3 documentation. The VALVE, SHUTTLE is available in: As Removed. Contact us for test documentation on your selected condition.
