Apparatus for regulating the flow of a subject fluid which includes immiscible fluids having differing densities such as oil and water, wherein plug means are provided which sink in oil and float in water, said plug means being positioned to control the flow of fluids through a scupper aperture. The plug means cause a sealing surface to move in and out of contact with the scupper aperture. Means are provided to enhance the separation of the sealing surface from the scupper aperture when fluid flow is to be permitted, and to increase the fluid tightness of the seal when fluid flow is to be prevented. Means are also provided for reducing the effects of turbulence in the subject flow, and hence to enhance the separation of the immiscible fluids from one another.
