Abstract: The present invention relates to a valve arrangement which includes a hydraulically actuatable non-return valve (1) and another, preferably electrically actuatable valve closure member (7), which are both positioned in a valve-accommodating bore (8) of the valve housing (12) in which the valve arrangement is received, wherein both valve closure members (17) cooperate with a valve seat member (4) in the valve housing (12). The non-return valve (1) is configured as a plate-type non-return valve with a flow opening (2) which is aligned coaxially to a first opening (3) of the valve seat member (4). Relative to the first opening (3) at least one bypass opening (5) is provided in the valve seat member (4) which is either closed or opened by a sealing surface (6) located to the side of the flow opening (2) of the non-return valve (1). A compact non-return valve (1) which is especially simple to make is thereby achieved.
