Abstract
Centrifugal separator having control valves 12 in the concentrated phase discharge passageway 10 for control of the concentration of solids in the concentrated phase. The control valves are hydraulically operated and have a control chamber 12c for the control fluid. The control fluid is clear phase obtained by communicating the control chamber 12c with the paring chamber 6 for the clear phase. Desirably the closing device of the valves is a resilient deformable tube membrane 12b.
