Overfill Prevention and In-Tank Equipment

OPW Overfill Prevention Valves are designed to prevent the overfill of USTs by providing a positive shut-off of product delivery.

OPW's 71SO-T Overfill Prevention Valve is the only UST Overfill Prevention Valve that is testable from the surface without removal from the tank, which allows operators to test in 60 seconds vs. 60 minutes per tank.
