As the float rises it actuates the ` <br /> external/internal magnetic couplers which release the flapper <br /> to be closed by the flow of product. As the float continues to i <br /> rise, the internal mechanism pushes the flapper further into 95% of rank <br /> the product flow to allow actuation at high or low flow rates. Volume <br /> This sudden reduction in flow caused by the primary flapper <br /> closing creates " line shock" to the fill hose which signals the <br /> delivery driver that the tank is nearing 95% capacity. As the <br /> float continues to rise to the 95%o fill level, the secondary Tank otfom <br /> - - - - - - - - - - - - - - - - - - - -1 - <br /> closes, completely stopping the flow of fuel. - - - - - - - <br /> 0 6" ( 152 mm ( Maximum <br /> ORDERING INFORMATION <br /> 708591901 Defender Series® overfill prevention valve with 5' (1524 mm) top drop tube, 8' (2438 mm) bottom drop tube <br /> 708591902 Defender Series® overfill prevention valve with 5' (1524 mm) top drop tube, 10' (3048 mm) bottom drop tube <br /> 708591921 Defender Series® overfill prevention valve with 5' ( 1524 mm) top drop tube, 8' (2438 mm) bottom drop tube, AGB compatible* <br /> 708591922 Defender Series® overfill prevention valve with 5' (1524 mm) top drop tube, 10' (3048 mm) bottom drop tube, AGB compatible* <br /> 708592901 Defender Series® overfill prevention valve with 10 ' (3048 mm) top drop tube, 8' (2438 mm) bottom drop tube <br /> 708592902 Defender Series® overfill prevention valve with 10 ' (3048 mm) top drop tube, 10' (3048 mm) bottom drop tube <br /> 708592921 Defender Series® overfill prevention valve with 10 ' (3048 mm) top drop tube, 8' (2438 mm) bottom drop tube, AGB compatible* <br /> 708592922 Defender Series® overfill prevention valve with 10 ' (3048 mm) top drop tube, 10' (3048 mm) bottom drop tube, AGB compatible' <br /> 708593901 Defender Series® overfill prevention valve, coaxial with 6. 5' ( 1981 mm) top drop tube, 8' (2438 mm) bottom drop tube <br /> 708593902 Defender Series® overfill prevention valve, coaxial with 6, 5' (1981 mm) top drop tube, 10' (3048 mm) bottom drop tube <br /> 708593923 Defender Seriese overfill prevention valve, poppeted coaxial with 6. 5' (1981 mm) top drop tube, 8' (2438 mm) bottom drop tube, AGB compatible* <br /> 708593924 Defender Seriese overfill prevention valve, poppeted coaxial with 6.5' (1981 mm) top drop tube, 10' (3048 mm) bottom drop tube, AGB compatible* <br /> 708594901 Defender Seriese overfill prevention valve only with top adapter, AGB compatible* <br /> 708594902 Defender Seriese overfill prevention valve only with coaxial top adapter, AGB compatible* <br /> 708535901 Roll crimping tool <br /> 708530930 Replacement roll crimper tool roller bit for retrofit with existing tool <br /> 708534901 Remote testing tool, 11 ' (3353 mm) long sectional/collapsible <br /> 708534902 Coaxial remote testing tool, 11' (3353 mm) long sectional/collapsible <br /> *Alcohol, gas, biofuel compatible (E-85, gasoline and Biodiesel) models come with hard coated anodized drop tubes for full compatibility. <br /> Defender OPV Replacement Parts <br /> 85039- 13T Spare drop tube seal <br /> 1103942 Spare adapter 0-ring <br /> 1103943 Spare Coaxial adapter 0-ring <br /> 708526901 Upper tube adapter kit <br /> 708529901 Coaxial Upper tube adapter kit <br /> 708542908 8' thread-on bottom drop tube assembly, 2-pk <br /> 708542910 10' thread-on bottom drop tube assembly, 2-pk <br /> 708542910AN 10 ' thread-on bottom drop tube assembly, 2-pk, AGB compatible <br /> 708542908AN 8 ' thread-on bottom drop tube assembly, 2-pk, AGB compatible <br /> 70821705 5' flanged top drop tube; order in multiples of 4 <br /> 70821725 5' flanged top drop tube, AGB compatible; order in multiples of 4 <br /> franklinfueling.com <br /> 3760 Marsh Rd . • Madison, WI 53718, USA <br /> Tel: USA & Canada +1800 225 9787 a Fax: +1608 838 6433 © 2020 Franklin Fueling Systems, Inc.
