What is the difference between a BOV (Blow-Off Valve) and DV (Diverter Valve)?
It basically comes down to the name. Traditionally a BOV is used to Vent to Atmosphere (VTA), while a Diverter Valve (DV) / By Pass Valve (BPV) is used to divert the excess charged air back into the charge pipe. It becomes a matter of semantics between who you ask in the community. VW/Audi (VAG) people like to call things diverter valves, while Honda users tend to refer to them as blow-off valves.
Both of our SB BOV and DV can be run in VTA or recirculated setups. The R35 and R55 Trident radial valves are atmospheric discharge only valves. The differences are listed here:
The BOV is pressure tested to seal up to 100psi, while the DV is tested up to 60psi.
The DV will flow slightly more than the BOV. From highest flow to lowest flow rates.
The DV is a more compact unit than the BOV, if clearance may be an issue, use these dimensions to help you.

Tuneability and setup possibilities. Both the BOV and DV can be fine tuned using the preload adjuster.
The BOV can be run in Pull mode with port combinations: B, or A+B
The DV can be run in Push or Pull mode with port combinations: B, A+B
