What is the purpose of a blow off valve and how does it work?

A blow off valve is actually a pressure release valve that releases turbo/boost pressure when the throttle plate is closed. While the turbo is still spinning and creating pressure, a wave of pressure will travel back to the turbocharger when the throttle closes, this will result in that the compressor wheel stalling the "compressor surge" and slowing it down very quickly.
