Product Description
The 84400-3 is a check valve for aircraft de-icing systems, allowing one-way flow while preventing backflow in pneumatic and fluid lines. This non-return valve maintains system pressure stability and protects downstream components from reverse flow during operation. Installed in wing and engine de-ice circuits, it isolates pressure sources and prevents air or fluid migration when system pressure drops.
Install with correct flow orientation per aircraft maintenance manual specifications. Verify IPC compatibility before installation to ensure proper system integration.
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.
Frequently Asked Questions
What is the CHECK VALVE (P/N 84400-3)?
The 84400-3 is a check valve for aircraft de-icing systems, allowing one-way flow while preventing backflow in pneumatic and fluid lines. This non-return valve maintains system pressure stability and protects downstream components from reverse flow during operation.
What hydraulic fluid type is the 84400-3 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 CHECK VALVE against your aircraft maintenance manual for fluid compatibility.
Does the 84400-3 come pressure-tested and certified?
