The purpose of valves is to prevent back flow of blood. In other words, it ensures that blood flows only in one direction . An atrioventricular (AV) valve is a valve located in the heart between the atria and the ventricles. In the right side of the heart, the AV valve is called the tricuspid valve .

The PCV valve is only one part of the PCV system, which is essentially a variable and calibrated air leak, whereby the engine returns its crankcase combustion gases to the air intake.he PCV system just diverts a small percentage of this air via the breather to the crankcase before allowing it to be drawn back into the intake tract again. It is an open system in that fresh exterior air is continuously used to flush contaminants from the crankcase and into the combustion chamber.
