A blow off valve protects turbocharged engines from compressor surge and reduces pressure on the engine.

Blow off valve is also known in the names compressor bypass valve, compressor relief valve, dump valve, diverter, recirc, pop off valves etc in different parts of the world. However, there can be slight differences in the function of valves described by the exact names.

The function of this valve is to suck off turbo pressure created in the intake system of a turbocharged engine. Blow off valve also serves in relieving pressure off centrifugally supercharged engine.

The air pressure created in the turbo is released into the atmosphere. A compressor bypass valve on the other hand re-circulates this pressure to the non-pressurized area of the intake, just before the turbo.

Wherever it leaves the pressure, these valves have only one function – relive excess turbo pressure caused by the rapid shutting of throttle under boost conditions. Only turbo boosted engines need to have a blow off valve. Without this, the pressure can be redirected to the turbo, which puts additional pressure on the turbo and minimizes its efficiency. It is one commonsense to think a blow off valve protects the turbo from additional pressure, prevents damage and increases life of the turbocharger.

The blow off valve comes with two pressure gauges to determine when to open the valve. The valve opens before the pressure is transferred to the engine. Blow off valve serves to safeguard your turbocharger and ensures longevity of the turbo.
