Abstract: An electromagnetic pressure regulating valve device for regulating a hydraulic pressure including at least one pressure regulating valve which includes a solenoid part having at least one bobbin holding an electric coil, a coil core and a movably guided armature; a valve part having at least one supply connection, one return connection, one load connection and one actuating element operated by the armature and cooperating with a valve seat; and an electronic part having at least one pressure sensor for measuring the hydraulic pressure present at the load connection.
