Features <br />• Simple, Easy and Quick Installation - No excavation or special manholes <br />required. <br />• Economical - Costs a fraction of expensive, complicated and difficult to install <br />valves. <br />• Furnished Complete - Supplied with new upper and lower drop tubes, mounting <br />hardware and thorough instructions for quick job site time. <br />• Completely Automatic Operation - No prechecks to perform, no resets, and no <br />overrides to be broken or abused. <br />• No Pressurization of the Tank - Operates directly from liquid level. <br />• Will Accept a Dipstick for Gauging. <br />• Retrofits Directly - For both new and existing tanks with 3" or 4" fill risers. <br />• Quick Drain Feature - Automatically drains hose when head pressure is relieved. <br />• Best Flow Rate in The Industry.* <br />* Test witnessed by Bowser-Morner, Inc., an independent laboratory. Results available <br />upon request. <br />Advantages of Overfill Prevention <br />Compared to Overfill Warning Systems: <br />• Completely Automatic Operation - Does not rely on the alertness or speed of <br />response of the delivery attendant, for certainty of overfill prevention. <br />• Keeps the Top of UST "Dry," per EPA Requirements - Eliminating possible leaks <br />at loose bung fittings and the need for double containment on vent lines. <br />• Does Not Rely on Pressure in the UST to Stop Flow - Allowing faster fill times <br />and reducing spill risk. <br />• Speeds Delivery Operations - Product flows unimpeded into the tank until the <br />hose "kick" that accompanies the valve shut-off provides a clear signal that the <br />liquid has reached the shut-off level. <br />• Simple and Inexpensive Installation - In both two-point and coaxial fill <br />applications, no additional excavation, manholes or vent piping are required. <br />Materials <br />Valve body: cast aluminum <br />Float: nitrile rubber, closed cell foam <br />Valve: aluminum <br />Seals: viton <br />Upper & lower Drop Tube: aluminum <br />Plastic parts: acetal <br />Hardware: stainless steel <br />
