Product Description
The a-255-2 is a shuttle valve for aircraft hydraulic and pneumatic systems. This component automatically directs the higher-pressure inlet to a common outlet, ensuring continuity between normal and standby pressure sources in critical control paths. Commonly installed in brake systems to select between normal and emergency/parking pressure sources.
The valve operates without external power, responding to pressure differential to maintain system redundancy. Install in-line with compatible fittings and verify proper operation and leakage per aircraft maintenance manual specifications.
