    Abstract: Disclosed is a proportional pressure control valve with a control piston (12) guided in a longitudinally movable manner in a valve housing (10), said control valve serving, by means of an actuating system (14), to selectively connect the connection points present in the valve housing, such as a pressure supply connection (P), a consumer connection (A) and a tank or return connection (T), wherein a first characteristic curve is produced between a control signal of the actuating system (14) and the flow volume or the control pressure (P), in relation to the consumer that can be connected to the consumer connection (A), wherein a second characteristic curve is produced for the consumer that can be connected to the consumer connection (A) of the valve housing (10) by means of a control device (65) after running through the first characteristic curve, the second characteristic curve differing to the first characteristic curve.

    Abstract: The invention relates to a valve device, in particular a double stop-check valve, preferably of the two-way valve type, comprising at least three fluid connections (1, 2, 3) provided in a valve housing (51), at least two valve elements (65, 67) that can slide in the valve housing (51), and at least one control device (71) for controlling the valve elements (65, 67). The valve is characterized in that at least one of the valve elements (65, 67) forms, together with parts (59/61) of the valve housing (51), a seat leak-tight closure part for the associated fluid connections (1, 2, 3).

    Abstract: A valve, in particular proportional pressure regulating valve, having a valve piston (12) which is guided in longitudinally movable fashion in a valve housing (10) and which can be actuated by means of an operation device (14), wherein the valve housing (10) has multiple fluid ports (P, A, T) and wherein, in one movement position of the valve piston (12), a fluid-conducting connection is produced between a pressure supply port (P) and a working port (A), and in another movement position, a further fluid-conducting connection is produced between the working port (A) and a tank port (T), is distinguished by the fact that the respective pressure difference that arises between the working port (A) and the tank port (T) as flow passes through the further fluid-conducting connection acts, by way of an actuation device (30), on the valve piston (12) such that the latter passes from a stop position (32), proceeding from which the further fluid-conducting connection is substantially shut off, into a fully open opening position, in which, in relation to the stop position (32), an enlarged opening cross section from working port (A) to tank port (T) is realized.
