The blood pressure and flow rate in veins is low. When the blood in them is moving upwards (e.g. in the legs) it can stagnate and may have a tendency to flow backwards in the vein. The valves prevent this back flow by closing.

The blood pressure and flow rate in arteries is high. Blood flow in the arteries cannot stagnate.
