Beschreibung
Zusammenfassung:	The invention relates to a quick acting control valve for a steam turbine, comprising a valve box (2) and a control valve cone (8) which is arranged in the valve box (2) so as to be displaceable along its center axis, whereby the control valve cone (8) can be brought into an open position in which the control valve cone (8), with its control valve cone surface (10), is lifted off the valve box (2), and into a closed position in which the control valve cone (8) rests against the valve box (2) with its control valve cone surface (10), and a quick acting valve piston (13) which is arranged in the valve box (2) so as to face the back (11) of the control valve cone facing away from the control valve cone surface (8), the quick acting control valve piston, on its outer peripheral edge (20), always resting on the valve box (2) in a steam-tight manner. The quick acting control valve further comprises a passage (15) through which steam (5) can pass from the side of the quick acting valve piston (13) facing away from t
