Here is wiki definition:
Definitions
A compressor bypass valve (CBV), also known as a compressor relief valve or diverter valve or BPV, is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged car when the throttle is lifted or closed. This air pressure is re-circulated back into the non-pressurized end of the intake (before the turbo) but after the mass airflow sensor.
A blowoff valve, (BOV, sometimes hooter valve, not to be confused with a dump valve) does basically the same thing, but releases the air to the atmosphere.

NO
From HKS- A slightly more reputable souce than wiki.
The difference is how the device works. A BPV remains open at all times, unless under boost. A BOV remains closed at all times, unless under vacuum. So, a BPV's state is changed with the introduction of Boost and a BOC's state is changed with the introduction of Vacuum.
The Vortech BPV (Blue) is not designed to recirculate, but rather vent to atmosphere. It can be changed to recirculate to the non pressurized size, ie before blower, but doing so does not change the inherrent nature of the BPV.

HKS Standard and Racing Bypass valves are push-type valves that utilize calibrated spring rate and vacuum line pressure to remain closed against the pressurized air in the charge pipe.
The New HKS Super SQV Racing blow off valve is a pull-type valve for high horsepower applications

this needs to release air at all times and close under boost to work with a vortech kit, or else compressor surge will happen...so is this a bypass or blow-off at the time being..buyer should be aware in the listing imo instead of getting it and realizing its not right..
