The 488-4SS11-2 is a stainless steel check valve for aircraft fuel systems. It permits flow in one direction while preventing backflow between tanks, pumps, or fuel system components. The valve opens under forward pressure and closes automatically when flow reverses, protecting against siphoning and cross-feed contamination.
Install with the marked flow direction arrow aligned to system flow. Leak-check per aircraft maintenance manual before returning to service. Cross-referenced to NSN 4820-01-114-2937.
