Abstract
A quick acting control valve for a steam turbine is provided. The quick acting control valve includes a valve box and a control valve cone which is arranged in the valve box so as to be displaceable along its center axis, whereby the control valve cone may be brought into an open position in which the control valve cone, with its control valve cone surface is lifted off the valve box and into a closed position in which the control valve cone rests against the valve box with its control valve cone surface, and a quick acting valve piston which is arranged in the valve box so as to face the back of the control valve cone facing away from the control valve cone surface, the quick acting control valve piston, on its outer peripheral edge, always resting on the valve box in a steam-tight manner.
