Valves regulate the flow of fluids in any system. In the human body, specifically, they keep blood from going to the improper places.
If you are asking about cylinder head valves there are two types. Intake valves allow fuel and air into the cylinder and exhaust valves allow the smoke to leave the cylinder. The piston moves down sucking in the fuel/air mixture with the intake valve open (intake stroke). The Intake valve closes at the bottom of the piston stroke then the piston moves up compressing the air and fuel (compression stroke). The spark plug ignites the fuel and air when the cylinder is back at the top causing an explosion that forces the piston back down ( power stroke ). The exaust valve then opens and the piston moves back up forcing out the exhaust (exhaust stroke). The exhaust valve closes and the intake valve opens and the cycle starts over.
