More Info

The OPW 71SO Series OPV Overfill Prevention Valve is a 2-Point Shut-off Valve designed to prevent the overfill of UST Underground Storage Tanks by providing a positive shut-off of product delivery. When the liquid level rises to about 95 Percent 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.If the delivery is not stopped and the liquid rises to about 98 Percent of tank capacity, the bypass valve closes completely. No additional liquid can flow into the tank until the level drops below a reset point.
