How can I Know if I Have an OPD Valve on my Propane Tank?

National code requires propane cylinders from 4-40 pounds have an OPD.   "Over-Fill Protection Device" (OPD) valves are manufactured with a specific shape to quickly identify them from older valves that do not have the OPD feature.  

Notice on the picture provided below.  The left image is of the older style valve and the three cornered handle on the valve on the right is the new style OPD valve.
