The 51204-8tt-20 is a relief valve designed to limit pressure in aircraft hydraulic circuits. This valve opens at a preset pressure threshold to protect pumps, lines, and actuators from overpressure conditions during normal operation or thermal expansion. Installed in hydraulic power systems on general and commercial aircraft, it maintains safe operating pressures by venting excess fluid when system pressure exceeds the valve's setting.
Installation and pressure setting verification should follow the applicable Aircraft Maintenance Manual and Component Maintenance Manual for your specific aircraft.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.

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 RELIEF VALVE against your aircraft maintenance manual for fluid compatibility.
Overhauled and repaired hydraulic components are pressure-tested per manufacturer specifications and include 8130-3 documentation. The RELIEF VALVE is available in: As Removed. Contact us for test documentation on your selected condition.
