What the heck is a blow off valve?

A blow off valve or BOV is a key component of any turbocharged engine. It is responsible for relieving pressure that builds up in the turbocharger system when the throttle is closed. This helps to prevent damage to the turbocharger and engine.

The types of blow off valve

Some of the common types of blow-off valves are:

  • Recirculating: This is the most common type of blow off valve. It sends the air back into the intake where it can be recirculated back through the engine.
  • Atmospheric: This type of blow off valve vents the air to atmosphere. This can cause issues with your car’s idle as well as make your car louder.
  • Hybrid: This type of blow off valve combines both recirculating and atmospheric blow off valves. It has a recirculating side for when the throttle is closed and an atmospheric side for when the throttle is open. This helps to prevent idle issues and makes your car quieter than an atmospheric blow off valve.

How do blow off valves work?

When the throttle is closed, the air that is being forced into the engine is now suddenly cut off. This causes a build-up of pressure in the turbocharger system.

The blow off valve is responsible for relieving this pressure by opening and releasing the air.

it is opened by the pressure that builds up in the turbocharger system. This pressure is sent to the blow off valve through a hose. then opens and allows the air to escape.

it is usually closed by a spring. When the throttle is opened, the pressure in the turbocharger system drops and the spring closes it.

Some blow off valves are equipped with a manual switch. This allows the driver to open the blow off valve at any time. This can be useful for venting pressure before turning the engine off. It can also be used to make your car sound louder.

How to choose the right blow-off valve for your vehicle?

The size of the blow off valve is important. If it is too small, it will not be able to relieve the pressure that builds up in the turbocharger system. If it is too large, it will cause the valve to open too often and can cause damage to the turbocharger system.

It should also be compatible with the type of turbocharger system that is in your vehicle. Recirculating blow off valves are the most common and can be used with any type of turbocharger system.

Atmospheric ones should only be used with vehicles that have a blow off valve recirculation hose. While Hybrid blow off valves can be used with any type of turbocharger system.

This type of valve should also be compatible with the type of engine that is in your vehicle. Recirculating valves can be used with any type of engine. Atmospheric valves should only be used with engines that are equipped with a blow off valve recirculation hose. Hybrid valves can be used with any type of engine.

Final Thoughts

In a brief, a blow-off valve is an important device that helps you prevent damage to the turbocharger and engine.
