Product Description
The Andair CK250-L-B is a bleed-type check valve for aircraft fuel systems. This machined aluminum valve uses a light shuttle and spring mechanism to prevent reverse flow in tank vent or fuel pump bypass lines while allowing controlled bleed-off for fuel expansion. The -B suffix designates the bleed configuration, enabling slight equalization pressure relief.
Install with the flow arrow oriented per your aircraft maintenance manual. Common in general aviation fuel systems where backflow prevention and expansion relief are required simultaneously.
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.
