OPW 71 SO allows easy installation (without breaking concrete) and requ no special manholes. The OPW 71 SO is a vapor -tight two- stage shut-off valve. When the liquid level rises to about 95% of tank capacity, the valve mechanism is released, closing automatically 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 capacity, the bypass valve closes completely. No additional liquid can flow into the tank until the level drops below a reset point. 71 SO Instruction Sheet Order Number: H15524PA O P W� A ooven coavwry Advantages of Overfill Prevention Compared to Overfill Wanting Systerns: Completely Automatic Operation 4> Speeds Delivery Operations - - does not rely on the alertness or product flows unimpeded into the tank speed, of response of the delivery until the hose "kick' that accompanies attendant for certainty of overfill the valve shut-off provides aclear prevention, signal that the liquid has reachedthe Keeps the Top of UST "Dry," per shut-off level.
