4 Basic Parts Of Blow Off Valve

A usual blow off valve is made up by an outlet and inlet port, a vacuum connection point and also a spring. It is made with high quality aluminium alloy and should come with accessories like flanges, bolts and gaskets.

Do you wonder what causes that loud and whoosh sound that you hear when cars pass by? Well the blow off valve is responsible for making cars sound like it’s going on a race track. But it is not just important because of the sound, but it also helps with an engines performance and also by preventing any damage to your car. It basically has two purposes; it is to prevent any compressor surges and also to reduce your engine from wearing out.

Now there are different types of these valves like the atmospheric valve, and the dual port valve that you can read more of in blow off valve selection guide. It is best for you to find out which type suits your vehicle and to further understand how this valve works here are its parts.

A usual blow off valve is made up by an outlet and inlet port, a vacuum connection point and also a spring. It is made with high quality aluminium alloy and should come with accessories like flanges, bolts and gaskets. You can even choose whether you would want a blue, silver, purple, or red color for your valve. New parts may either have new additions or less, depends on what type of valve it is. So how does this really work?

It protects any compressor surges from your turbo. When you release the cars’ throttle while you’re on boost, it works by opening and dumping the inlet pressure. Surges like these occur when you release the throttle, the compressed air forces back to the turbo, which can possibly damage it. This valve will quickly react to this situation and it will let go of the compresses air then giving you a distinct sound so that you will be assured that the valve is working properly.

These valves are mounted on the intake plumbing of the engine; it is seen among the throttle plate and the turbocharger compressor. The air that is pressurized usually is forced back to the compressor and then vented into the air through a pressure relief valve. It recirculates the air into the intake stream. When you shift gears while driving, it allows the compressor to still spin by allowing the air to be rerouted than having to force it to the turbocharger compressor, allowing the air to spin freely without having to slow down can result in better performance for your vehicle.

The atmospheric valve is the type of valve that releases air into the atmosphere, resulting to that horn like noise that can be very loud. Some people get valves just to have this sound effect though it may be irritating to others. When you purchase a valve, you should be sure to see if the parts seen in the picture above are all in it because there are also fake calves available already in the market which you should be careful of because of improving the performance of your car it might just make it worse. So always be careful when you purchase the right blow off valve for your car.
