DEFENDER . , . SERIESO OVERFILL t 3} : PREVENTION 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 conditions . Simple to install, service and test remotely, the Defender Series® w OPV is the industry ' s most versatile overfill prevention valve . MEMO • 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 ® ATEX approved any potential product or vapor leak points . • After cutting to length in the field, the upper drop tube is • CARB certified roll-crimped onto a top adapter outfitted with two 0-rings and Dimensions then threaded onto the top of the valve body, eliminating the need for drilling , rivets , epoxy, and flaring tools , 9.97' ( 1i%� mm) • Bottom drop tube is cut in the field and threaded onto the bottom of the valve ensuring straight installation . , ' 1440 5 mm) • The roll-crimp/thread method of installing drop tubes ensures proper alignment of the drop tubes with the rest 95% Shutoff 11 of the OPV assembly, making installation and removal of leiLevel the entire assembly smooth . t • Damaged drop tubes can be easily replaced instead of z ' having to purchase an entire new assembly. ` • Fully compatible with gas , gas/alcohol blends , diesel K and biodiesei . • Compatible with industry standard 4 ' drop tubes allowing s 17.49' i8. i0 retrofit Into existing Installations . (442 mm) (447 Orn) • 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 , w • 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.
