SERVICE STATION HARDWARE jFranklinFuelingsystems I UNDERGROUND STORAGE TANK EQUIPMENT r • TM - L; Defender Series X Overfill Prevention Valve The Defender Series'" overfill prevention valve ( OPV ) is a self contained two -stage positive shut-off valve that prevents the overfill of an underground storage tank ( UST) during a gravity-fed product delivery . The Defender Series"' OPV employs a revolutionary magnetically-coupled actuator system to provide positive shutoff . This unique method of shutoff eliminates any penetrations in the valve , making it both vapor and leak tight . The o Defender SeriesTMOPV provides safe , rapid , and reliable fuel drops for the broadest range of fuel applications and environmental Top Adapter conditions .
