Title: Oil Stop Valve : Oil Spill Containment Research and Development Project.

Technical Report ·
OSTI ID:5171965

This report summarizes the research and development project conducted by the Civil Engineering Section, Division of Substation and Control Engineering, to determine the effectiveness of the oil stop valve for use in the Bonneville Power Administration's Oil Spill Containment and Countermeasure Program. The most attractive alternative to lagoons and separator tanks was found in the oil stop valve manufactured by AFL/Clark Industries of Riviera Beach, Florida. This small, direct-acting and relatively inexpensive valve requires little maintenance and can either be employed independently, using existing drain lines for effluent storage, or in conjunction with oil separator tanks and lagoon systems. The AFL/Clark valve requires no power and has only one moving part, a ballasted float having a specific gravity between that of oil and water. In water, the float rides above the throat of the discharge pipe allowing water to flow out. When oil enters the water the float begins losing its relative bouyancy and sinks until it seats itself over the throat of the outlet, closing the valve. Usually installed in a manhole within a typical storm drainage system, the valve backs spilled oil into drainways and contains it for temporary storage within the switchyard.
