Blow Off Valves

Blow Off Valves

A blowoff valve (BOV), dump valve or compressor bypass valve (CBV) is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. These valves relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to the atmosphere (BOV case), making a distinct hissing sound, or recirculate into the intake upstream of the compressor inlet.
