There are two different types of valves for your car, an atmospheric valve one which vents out the air to the atmosphere, a recirculating valve which plumbs the air back. There is now also a dual port BOV  that has a plumb-back and trumpet attached to it which allows you to decide what type of release you would want to use or if you want to use both types at the same time. The main difference between the three of them is how they get rid of the vented boost pressure and also what sound they make when you release the pressure.

The atmosphere BOV works by venting out the extra boost pressure of the system into the atmosphere. It usually produces that popular “whoosh” sound when you release the pressure. Here’s what it looks like:

The recirculating BOV or commonly known as the “Plumb-back” type of valve works by venting the pressure in the intake system even which is before the turbocharger inlet. It actually does the opposite of the atmospheric valves thus making these types almost silent if you compare the both of them. These valves are a good choice if you are most likely travelling in mud or dirt because it offers protection against any damage caused by sand, mud, or also dirt. It is commonly used for those off-road and rally cars.

Lastly, is the Dual Port which is released by Turbosmart as a hybrid atmospheric type of valve that works according to your type of selection. You can choose to use the atmospheric, plumb back or even both types because it consists of a trumpet and also a plumb-back attachment which can be a good choice for cars that have management systems that are air sensitive.
