The 204-076-437-003 is a check valve that allows fluid flow in one direction while blocking reverse flow in aircraft hydraulic systems. Installed in hydraulic return lines, it isolates subsystems and protects pumps from backpressure and contamination. The valve opens when forward pressure exceeds the cracking pressure threshold and closes automatically when flow reverses.
Installation requires correct orientation per the aircraft maintenance manual and verification against the Illustrated Parts Catalog to ensure system compatibility and airworthiness compliance.
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 CHECK 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 CHECK VALVE is available in: As Removed. Contact us for test documentation on your selected condition.
