What overfill prevention valves do: Overfill prevention valves for underground storage tanks prevent fuel spills that might occur if the tank was overfilled during product delivery. Overfill prevention is required for USTs filled with more than 25 gallons of product at one time.
How overfill prevention valves work: There are two primary types of overfill prevention valves for USTs – automatic shutoff valves and flow restrictor valves. An automatic shutoff valve stops the flow of product when it reaches a certain level in the tank. Flow restrictor valves slow product flow when it reaches a certain level, which alerts the operator to stop delivery. Aboveground storage tanks require a special overfill prevention valve designed for that application.
