ABSTRACT:
The invention relates to a valve, more particularly for a superheated steam conversion station, having an inlet and an outlet which can be closed by a closure member extending into the inlet or outlet, and a draw-off via which a component flow of the steam can be drawn off in the form of booster steam from the valve chamber (2) of the valve casing in dependence on the position of the closure member; the inlet or outlet is constructed with at least one chamber connected to a booster steam drawing-off bore with which a fixed wall of the chamber is formed; and when the valve is closed the chamber, which is sealed off from the pressure side of the valve by sealing faces of the closure member, is connected to said pressure side of the valve with the first lifting of the closure member, while the inlet or outlet is not yet opened or not yet completely opened.
