SERVICE STATION HARDWARE jFranklinFuelingSystems I UNDERGROUND STORAGE TANK EQUIPMENT • TM 1 Defender series Overfill Prevention . l Valve i 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 Defender Series" OPV provides safe , rapid , and reliable fuel drops for the broadest range of fuel applications and environmental Top Adapter conditions . Simple to install , service and test remotely, the Defender Series'"' OPV is the industry' s most versatile overfill prevention valve , Highlighfs Specifications • Magnetic coupler actuates the interior primary Approvals/ Certifications flapper assembly and secondary shut-off valve when • ULc listed . the float rises outside of the valve , eliminating valve body penetrations and any potential product or • ATEX approved . vapor leak points , • After cutting to length in the field , the upper drop Dimensions tube is roll-crimped onto a top adapter outfitted with two 0-rings and then threaded onto the top of the valve body , eliminating the need for drilling , rivets , epoxy, and flaring tools . 1 .75^ • Bottom drop tube is cut in the field and threaded onto (44 .5+mm) the bottom of the valve ensuring straight installation . 95% Shutoff • The roll-crimp /thread method of installing drop tubes Level ensures proper alignment of the drop tubes with the rest of the OPV assembly, making installation and removal of the entire assembly smooth , • Damaged drop tubes can be easily replaced instead of having to purchase an entire new assembly . • Fully compatible with gas , gas /alcohol blends , diesel 17 .40° 19, 40" and biodiesel . (442 n1m) (467 mm) • Compatible with industry standard 4" drop tubes allowing retrofit into existing installations . • The entire OPV assembly remains within the 4" inner diameter of the riser preventing interference with other tank components and also allowing removal even while the tank is full . • Actuates in both low and high flow applications and functions within a broad range of flow rates from 25 gpm to 370 gpm (95 Ipm to 1 ,400 Ipm ) . • The remote testing tool allows for remote testing of the primary functionality without having to remove the OPV from the riser.
