Our Patented Design is the Most Effective and the Most Versatile. The OPW 61SO Overfill Prevention Valve is designed to prevent the overfill of underground storage tanks by pro- viding a positive shut-off of product delivery. The shut-off valve is an inte- gral part of the drop tube used for grav- ity filling. The OPW 61SO allows easy installation (without breaking concrete) and requires no special manholes. The OPW 61SO is a two-stage shut- off valve. When the liquid level rises to about 95% of tank capacity, the valve mechanism is released closing automat- ically with the flow. This reduces the flow rate to approximately 5 gpm through a bypass valve. The operator may then stop the filling process and disconnect and drain the delivery hose. As long as the liquid exceeds the 95% level, the valve will close automatically each time delivery is attempted. If the delivery is not stopped and the liquid rises to about 98% of tank capac- ity, the bypass valve closes completely. No additional liquid can flow into the tank until the level drops below a reset point. Models of the 61 SO are available to meet virtually any UST application including two point, coaxial, poppeted coaxial and remote fill. The 61SO-3000 provides two point overfill protection for 3" riser pipes, and the 61SO-1000 and 6150-100C(CARB) feature a grooved tube design for use with tank gauging systems. Methanol and CARB (vapor tight) approved models are also available. The OPW 61 SO is approved by the New York City Fire Department. (Approval #4902). ER F I L L Features of the 61SO Series: ♦ Simple, easy and quick installation — no excavation or special manholes required. ♦ Economical — costs a fraction of expensive, complicated and difficult to install valves. ♦ Furnished complete — supplied with new upper and lower drop - tubes, mounting hardware and thorough instructions for quick job site time. ♦ Completely automatic operation — no prechecks to perform, no resets, and no overrides to be broken or abused. ♦ No Pressurization of the tank — operates directly from liquid level. ♦ Will accept a dipstick for gauging. ♦ Retrofits directly — for both new and existing tanks with 3" or 4" fill risers. ♦ Quick drain feature — Automatically drains hose when head pressure is relieved. ♦ Best flow rate in the industry.* Advantages of Overfill Prevention Compared to Overfill Warning Systems: ® Completely automatic operation — does not rely on the alertness or speed of response of the delivery attendant — for certainty of overfill prevention. ® Keeps the top of UST "dry", per EPA requirements — eliminating possible leaks at loose bung fittings and the need for double containment on vent lines. ♦ Does not rely on pressure in the UST to stop flow — allowing faster fill times and reducing spill risk. ® Speeds delivery operations — product flows unimpeded into the tank until the hose "kick" that accompanies the valve shut-off provides a clear signal that the liquid has reached the shut-off level. ® Simple and inexpensive installation— in both two-point and coaxial fill applications, no additional excava- tion, manholes or vent piping is required. ][ION VALVES * Test witnessed by Bowser-Morner, Inc., an independent laboratory.
