What does a compressor safety valve do?

This compressor safety valve acts as a critical protective component within the air brake system by automatically venting excess air when pressure exceeds safe limits. It is engineered to protect the compressor housing and pneumatic lines from damage caused by overpressure, ensuring stable operation of the braking system.
