    • The present invention provides a valve device incorporating two valves, for example a stop valve and a control valve, housed in the same side of a common casing. The proposed valve device (10) comprises an inlet port (14) and an outlet port (16) connected by a fluid flow channel (18). The valve device (10) further includes a first valve and a second valve housed in a common casing (13). The first valve comprises a first valve head (22) mounted on an annular-shaped first spindle (20). The second valve comprises a second valve head (26) mounted on a second spindle (24), said second spindle (24) extending concentrically and slidably through said annular-shaped first spindle (20). The first and second valves are displaceable along a common axis (28) and operable to influence fluid flow between said inlet port (14) and said outlet port (16) through said flow channel (18).

    • The invention relates to a method for actuating valves for controlling a flow path of especially a medical treatment machine, comprising a plurality of processes for establishing flow paths by actuating a group of valves, every process requiring a group of valves that are suitable for carrying out said process, so that other processes cannot change the switched state of said valves, and every process deciding on the release of the valves required by it. The invention further relates to a method for monitoring the actual and/or planned state of a plurality of valves in the control of a flow path of an especially medical treatment machine. Said method comprises the following steps: determining the actual and/or planned switched state of the valves, determining the connections resulting from the switched state of the valves, comparing the resulting connections to a predetermined plurality of inadmissible connections. The invention further relates to machines, especially medical treatment machines, which comprise corresponding valve or valve actuator controls.
