Abstract

A centrifugal separator having outlet valves 11 (FIG. 2) at the periphery of the drum for discharge of concentrate. The valve piston 20 is shielded from drum pressure by the valve casing 17 and the position of the valve piston is controlled by control fluid introduced through bore 26. The valve nozzle 18 is provided with a notch 19 for control of the valve opening size. This facilitates control of the rate of discharge of concentrate in dependence of the operating conditions.
