"The PCV Valve, or Positive Crankcase Ventilation valve is an emission control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned. The PCV system is one of the oldest emission control devices, and also one of the most beneficial. Besides totally eliminating crankcase emissions as a source of air pollution, the constant recirculation of air through the crankcase helps remove moisture which otherwise would cause sludge to form. Thus the PCV valve extends the life of the oil and engine. The PCV valve requires little maintenance. The valve should be replaced somewhere around 20,000 miles(see the vehicle owners manual for service intervals)".

Here is another excellent link:
Explation with visuals about PCV Valves

There is no need to get a new one; most of the times you can clean yours. Sink the PCV valve in carb cleaner or something similiar, let it sit for while there and then clean it with a dry cloth or whatever you think is better for you. All you can find inside the PCV valve is oil build-up, thats why it is so simple to clean it up.
