SERVICE STATION HARDWARE UNDERGROUND STORAGE TANK EQUIPMENT Autolimiter II Automatic Overfill Prevention Valve ® The EBW® brand Autolimiter® overfill prevention valve is a self contained two-stage positive shut-off valve designed to prevent the overfill of an underground storage tank (UST) during a gravity fed product delivery. When the liquid level of the UST reaches about 92% of the tank capacity during a fill, the product in the tank raises the lower float of the valve. The primary poppet of the valve is then released and reduces flow to about 10% of normal flow. The sudden reduction in flow created by the closing of the primary poppet provides “line shock” to the fill hose notifying the transport delivery driver the tank is nearing 95% capacity. The transport delivery driver can then stop filling the tank, disconnect and drain the delivery hose. The upper float will close off the product flow when the product level reaches 95% of the tank capacity. Highlights •Two-stage, spring-loaded shut-off flapper reduces line shock. •Vertical float design allows for valve to be removed even when tank is full. •Inspection test port. •Bottom tube threads on (except for -04 models). •Designed solely for use in underground storage tanks. For gravity drops only. No attempt should be made to utilize this product with aboveground storage tanks. The valve would not function, creating a very dangerous condition.
