OPW - 61SOM-412C-EVR - Overfill Prevention Valve

The OPW 61SO Overfill Prevention Valve is designed to prevent the overfill of underground storage tanks by providing a positive shut-off of product delivery. The shut-off valve is an integral part of the drop tube used for gravity filling. The OPW 61SO allows easy installation (without breaking concrete) and requires no special manholes.

Advantages of Overfill Prevention Compared to Overfill Warning System

• 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 excavation, manholes or vent piping are required.
