Product Description
The 9840034e is a non-return (check) valve that permits flow in one direction while blocking reverse flow. This valve prevents backflow in aircraft bleed-air environmental control system lines, maintaining system integrity during engine operation and shutdown cycles. Constructed to SAE aerospace standards (ARP4946A), the valve features a poppet mechanism that opens under forward pressure and closes automatically when pressure reverses.
Installation requires correct flow orientation and torque specification per the aircraft Maintenance Manual. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation.
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.
