Product Description
The 3d3520-260 is a check valve assembly that permits flow in one direction while preventing reverse flow in aircraft systems. Installed in pneumatic bleed-air lines, this valve protects against backflow between air sources during operation. The assembly uses a spring-loaded poppet mechanism to maintain one-way flow integrity.
Installation requires verification against the aircraft's Illustrated Parts Catalog and adherence to maintenance manual procedures, including pressure testing and leak checks to ensure proper sealing.
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.
