FAA & EASA certified non-return valve 2 inch repair and overhaul.
About the Non-Return Valve 2 inch
A two-inch non-return valve is a check valve that permits airflow in one direction within the pneumatic and air management ducting while preventing reverse flow, protecting upstream sources and preventing backflow between bleed or cross-bleed manifolds. It typically uses a spring-loaded flapper or poppet that opens under forward pressure and seats closed when flow reverses. Because it operates passively in a high-temperature, pulsating air stream, its principal degradation modes are seat and seal erosion, spring fatigue or breakage, flapper hinge wear, sticking, and reverse leakage past a worn seat. Inspection commonly reveals leakage in the closed direction, sluggish opening, and worn or chattering elements. Overhaul restores the seat, flapper, hinge, and spring to ensure free forward flow and tight, reliable reverse sealing.
