To let the fuel and air into the cylinder and to let the exhaust out. Inside a motor there is a space (cylinder) where fuel and air is compressed by a piston then ignighted by a sparkplug. A valve is a little round disk with a stem coming out of its middle. The valve moves into that space creating an outlet around it past the stem. Every cylinder will have at least two valves.. 1 for fuel & air and 1 for exhaust. Hope that was helpful I tried to keep it simple as possible.

With springs.
yes if t belt breaks it usually bends valves
valves are use in four stroke engine, and ports are use in two stroke engine.
if you see the difference between valves
Incomplete combustion in an engine indicates that all of the fuel has not been burnt. Incomplete combustion can cause clogging and damage to the valves in the engine of a car.
Valves will clatter if the engine is overheating.Valves will clatter if the engine is overheating.
It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.
On a 1996 Ford Taurus : The 3.0 liter " Vulcan " V6 engine has ( 2 valves per engine cylinder , total of 12 valves ) The 3.0 liter " Duratec " DOHC , V6 engine has ( 4 valves per engine cylinder , total of 24 valves )
On a 1999 Ford Taurus : If you have the 3.0 " Vulcan " V6 engine ( which is an Over Head Valve / pushrod design engine ) there are ( a total of 12 valves , 2 valves for each engine cylinder ) If you have the 3.0 " Duratec " V6 engine ( which is a Dual Over Head Cam design engine ) there are ( a total of 24 valves , 4 valves for each engine cylinder )
Most stock engine valves are made from steel alloys. Higher performance/ aftermarket valves are stainless steel, Titanium or inconel (exhaust valves).
An engine may have two, three, or four valves per cylinder.
Worn engine rings or valves Worn engine rings or valves
An engine may have two, three, or four valves per cylinder.
Valves per cylinder makes one's engine more powerful or less powerful. A engine that has 2 valves per cylinder is better that a engine that has only one.
There are two types of valves in an engine. The valves are located in the head. There are exhaust valves and fuel intake valves
That would depend on which engine you have : The 3.0 liter " Vulcan " V6 engine has a total of ( 12 valves / 2 valves per cylinder ) The 3.0 liter DOHC " Duratec " V6 engine has a total of ( 24 valves / 4 valves per cylinder )
16 engine valves.
