Abstract
A product disconnect is provided for cutting off product flow between a product tank and an associated metering system. The product is instead directed to a product cleanout where an operator can empty the product tank without sending product through the metering system. The product disconnect may consist of one or more rotary cutoff valves which are selectively movable between an open position allowing product to flow into metering system and a closed position where product is instead directed to a product cleanout.
