A blow–off valve (BOV), dump valve or compressor bypass valve (CBV), is a pressure release. A blowoff valve , (sometimes hooter valve or BOV ) performs the same task but releases the air into the atmosphere instead of recirculating it. The pressure switch turns the compressor on and off based on the pressure build up.

If the pressure reaches the higher limit, then the pressure switch turns off the compressor.

When pressure switch fails, your compressor plunges in more and more air. At that point, your second safety measure, the pressure relief valve kicks in. We´ve chosen to illustrate the function of an atmospheric blow off valve, even if a. A blow-off valve is simply a form of pressure release system that you would normally find in turbocharged gasoline engines.

Notice the mention of the word ‘gasoline engines’ here, because we get a lot of questions regarding the use of blow-off valves in high-performance turbocharged diesel engines, or those fitted with CRDI or Common-Rail Direct Injection. The air compressor unloader is valve is a small, but important, part of the reciprocating piston compressor. It blows off the pressure inside the discharge pipe when the compressor stops. There is another type of unloader valve , which can be found at the inlet of rotary screw compressors, also called inlet valve or loading valve ).
