If the separating temperature is to remain constant, what is the relationship between the specific gravity of the oil and the required size of the regulating ring? Illustration MO-0113

Correct Answer: Option B — The larger sized regulating rings are designed to be used with oils of lower specific gravities.

Gravity disc (regulating ring) sizing is inversely related to the specific gravity of the oil being processed at a constant operating temperature. Larger regulating rings feature smaller internal dam diameters, designed specifically to handle oils with lower specific gravities.
