What is the function of wing isolation valves in the bleed air system?

The function of wing isolation valves in the bleed air system is to isolate each wing manifold section. This isolation allows for maintenance and operational flexibility by enabling the system to shut off airflow to a specific wing's bleed air system without affecting the other wing. By isolating the wing sections, the aircraft can maintain safety and performance even if one section requires servicing or if there is a failure in one wing's system. This is particularly important in ensuring that the aircraft can still function effectively and safely with redundancy in its systems, allowing for continued operation despite partial system disruptions.

In the context of wing isolation valves, the ability to manage airflow and maintain operational integrity is a critical feature, especially in complex aircraft systems where different sections can operate independently.
