Abstract (en)
[origin: DE19807503A1] The valve arrangement has a valve housing (2,5) with inlet and outlet connections, a seal seat closed by a sealing disc and an actuator (3,4). The sealing disc can be rotated about an axis and set in rotation by the actuator. An overlapping area formed by the through opening (19a,19f) in the disc (15) with the opening (20) enclosed by the seat (16), depends on the rotation angle of the disc with respect to its rest position.
