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).
