Modular Overfill Prevention Systems

Overfill Prevention Valves/Assemblies - A1100EVR Guardian Modular Overfill Prevention System

The highly customizable Modular Overfill Prevention Valve easily accommodates upgrades and mitigates installation errors. Additionally, the modular construction of the assembly alleviates steep shipping costs for both new OPVs and replacement parts.

 

All assemblies are vapor tight and meet EPA 40 CFR Part 63 requirements. No epoxy needed. All standard A1100 variants are acceptable for use with up to E25 ethanol blend gasoline and B20 biodiesel blends. A higher percentage of ethanol or biodiesel requires the use of the “E” variant. Every OPV is available with anodized top tubes (champagne color for easy identification) to prevent corrosion build-up between the drop tube and the riser pipe.
