Franklin Fueling Systems DEFENDER SERIES® OVERFILL PREVENTION VALVE The Defender Series®Overfill Prevention Valve (OPV) prevents the overfill of an underground storage tank during a gravity-fed product delivery. It 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. This also allows for remote compliance testing of the primary functionality at grade level without having to remove the OPV from the tank. Drop Tube Adapter HIGHLIGHTS SPECIFICATIONS • Magnetic coupler actuates the interior primary flapper Approvals & Certifications assembly and secondary shut-off valve when the float rises outside of the valve, eliminating valve body penetrations and • CARB certified, VR-101-U (FFS) and VR-102 (OPW®). any potential product or vapor leak points. • ATEX 2014/34/EU approved. • After cutting to length in the field, the upper drop tube is • EN 13616 certified. roll-crimped onto a top adapter outfitted with two 0-rings and e KIWA BRL-K636/03 certified. then threaded onto the top of the valve body, eliminating the need for drilling, rivets, epoxy, and flaring tools. • UL 2583 listed and ULc listed, MH21090. • Bottom drop tube is cut in the field and threaded onto the • For all vapor control and liquid control products covered bottom of the valve ensuring straight installation. by UL 2583 automotive fuels, only those fuels formulated • The roll-crimp/thread method of installing drop tubes ensures in accordance with 40CFR80, "Regulation of Fuels and proper alignment of the drop tubes with the rest of the OPV Fuel Additives," and meeting the following ASTM fuel assembly, making installation and removal of the entire specifications and blend limits: assembly smooth. • ASTM D975 diesel with or without biodiesel blends up • Damaged drop tubes can be easily replaced instead of having to 5% (135) to purchase an entire new assembly. .
