Abstract (en)
[origin: WO2015149906A1] 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.
