The EBW Warden AST Overfill Limiter is designed for Aboveground Storage Tanks (AST). Where the product is pumped from the transport truck to the AST, the auto limiter will stop the flow when the level in the tank reaches a predetermined point. The EBW Warden® is designed to provide a positive shut-off during a pressurized fill delivery on an above ground storage tank. It eliminates spills and overfills, avoiding costly cleanup expenses and ground contamination. The Warden is fully adjustable to provide shut-off in various height and capacity above ground tanks. The Warden is designed to fit into a 4” fill riser making installation on new and existing locations simple and quick. The cylindrical float design eliminates interference with tank walls and cross bracing. The 709-400 models require 8" to 9" ullage. The 709-420 model was designed with inverted floats to be used in smaller or rectangular tanks. The 709-420 model requires 4" minimum ullage.
