i i UNDERGROUND STORAGETANK EQUIPMENT DEFENDER SERIES ° 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 Defender Series" OPV provides safe , rapid , and reliable fuel drops for the broadest range of fuel applications and environmental conditions . Simple to install , service and test remotely, the Defender Series" OPV is the industry ' s most versatile overfill prevention valve , SPECIFICATIONS • Magnetic coupler actuates the interior primary flapper Approvals/Certifications assembly and secondary shut-off valve when the float rises . ULc listed outside of the valve, eliminating valve body penetrations and any potential product or vapor leak points . • ATEX approved • After cutting to length in the field , the upper drop tube is • CARB certified roll-crimped onto a top adapter outfitted with two O-rings and Dimensions then threaded onto the top of the valve body, eliminating the need for drilling , rivets, epoxy, and flaring tools . 3 .97 • Bottom drop tube is cut in the field and threaded onto the bottom of the valve ensuring straight installation . 1 .75" • The roll-crimp/thread method of installing drop tubes (44.5+mm ) ensures proper alignment of the drop tubes with the rest 95 of the OPV assembly, making installation and removal of Shutoff the entire assembly smooth . Level • Damaged drop tubes can be easily replaced instead of having to purchase an entire new assembly. • Fully compatible with gas , gas/alcohol blends , diesel and biodiesel . • Compatible with industry standard 4' drop tubes allowing 17 .40' 18 .40" retrofit into existing installations . (442 n,m ) (467 mm ) • 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. * Franklin Fueling Systems
