It isolates the air supply to protect the rest of the system if an attached component fails, helping maintain brake safety. The valve opens at 70 PSI and closes at 60 PSI, with an internal check valve to prevent backflow. You typically replace it when it fails to hold pressure, leaks, or doesn’t open/close at the correct pressures.
