OPW 71SOM, CARB /EVR Approved for use with E85, vapor-tight 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 71SO allows easy installation (without breaking concrete) and requires no special manholes.
Materials
- Nickel plated aluminum, anodized aluminum, stainless steel and other compatible materials; no exposed bare aluminum
- Stainless steel lower tube included, no epoxy needed in field
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 excavation, manholes or vent piping are required.
Features & Benefits
- CARB /EVR Approved for use with E85
- Constructed of nickel plated aluminum, anodized aluminum, stainless steel and other compatible materials; no exposed bare aluminum
- Stainless steel lower tube included, no epoxy needed in field
- Designed for tanks up to 10 ft bury and 10 ft in diameter
- Robustly designed for long term vapor-tight performance in aggressive fuels
