The system includes an inlet channel (100, 310) and an outlet channel (200, 320). The inlet channel has an inlet port at a first end configured to be connected to a patient, and a second end with an at least part-annularly shaped aperture (314). The outlet channel has an outlet port at a first end, and an aperture (313) at a second end. The system further comprises a flow channel arranged concentrically outside the at least part-annularly shaped aperture. The flow channel is in fluid connection with the outlet channel. The at least part-annularly shaped aperture of the inlet channel and the aperture of the outlet channel are separated by a seating means (312). The at least part-annularly shaped aperture of the inlet channel and the flow channel are separated by the seating means. ## Claims ### Claim 1 A valve comprising: an inlet channel and an outlet channel; said outlet channel has an outlet port at a first end, and an aperture at a second end; said inlet channel has an inlet port at a first end, and a second end with an aperture, said aperture being at least part-annularly shaped, wherein said aperture of said inlet channel is concentrically or co-axially arranged surrounding said aperture of said outlet channel; a flow channel is arranged concentrically outside said aperture of said inlet channel, and said flow channel is in fluid communication with said outlet channel; said aperture of said inlet channel and said aperture of said outlet channel are separated by a seating means, and said aperture of said inlet channel and said flow channel are also separated by said seating means; a disc is movably arranged between a closed position abutting said seating means in which fluid communication is prevented between said aperture of said inlet channel and said flow channel and between said aperture of said inlet channel and said aperture of said outlet channel, and an open position in which said aperture of said inlet channel is in fluid communication with both said flow channel and said aperture of said outlet channel; wherein flow through the valve is controlled by an applied mechanical force to said disc. ### Claim 2 (depends on 1) The valve according to claim 1, wherein said aperture of said inlet channel is circularly shaped. ### Claim 3 (depends on 1) The valve according to claim 1, wherein said aperture of said outlet channel is circularly shaped. ### Claim 4 (depends on 1) The valve according to claim 1, wherein the valve includes two ports for connecting pressure sensors for measuring a valve inlet pressure and a valve outlet pressure. ### Claim 5 (depends on 4) The valve according to claim 4, wherein the pressure ports are configured to be connected to bacteria filters or tubes. ### Claim 6 (depends on 1) The valve according to claim 1, wherein the disc has pressure equalizing flow paths. ### Claim 7 (depends on 1) The valve according to claim 1, wherein a pressurized disc area of said disc, when in use, has the same size as an area of said aperture of said inlet channel. ### Claim 8 (depends on 1) The valve according to claim 1, further comprising a shaft connectable to an actuator for moving the shaft up and down and thereby closing and opening the valve. ### Claim 9 (depends on 8) The valve according to claim 8, further comprising a gasket which acts as a barrier between said shaft and said disc. ### Claim 10 (depends on 9) The valve according to claim 9, wherein said size of said gasket is selected to either over compensate or under compensate for an outlet pressure. ### Claim 11 (depends on 9) The valve according to claim 9, wherein a size of said gasket is selected to make said valve independent of said outlet pressure. ### Claim 12 (depends on 1) The valve according to claim 1, wherein said seating means are arranged as a continuous seating means around said aperture of said inlet channel. ### Claim 13 (depends on 1) The valve according to claim 1, wherein said seating means are two valve seats, a first valve seat is arranged to separate said aperture of said inlet channel from said flow channel, and a second valve seat is arranged to separate said aperture of said outlet channel from said aperture of said inlet channel. ### Claim 14 (depends on 1) The valve according to claim 1, wherein said first valve seat, and said second valve seat are circularly shaped. ### Claim 15 (depends on 1) The valve according to claim 1, wherein said disc is a diaphragm means. ### Claim 16 A method of stabilizing a valve, comprising: arranging a disc to be movable between a closed position abutting said seating means in which fluid communication is prevented between an at least part-annularly shaped aperture of an inlet channel and a flow channel, said flow channel in fluid connection to an outlet channel, and between said at least part-annularly shaped aperture of said inlet channel and an aperture of said outlet channel, and an open position in which said at least part-annularly shaped aperture of said inlet channel is in fluid communication with both said flow channel and said aperture of said outlet channel, and controlling flow through the valve using an applied mechanical force to said disc, wherein said aperture of said inlet channel is concentrically or co-axially arranged surrounding said aperture of said outlet channel. ### Claim 17 (depends on 16) The method according to claim 16, comprising controlling an actuator for adjusting a distance between said disc and said seating means, and thereby controlling the flow through the valve. ### Claim 18 (depends on 16) The method according to claim 16, comprising applying the applied mechanical force using an actuator, and controlling the applied mechanical force applied by said actuator to allow a controlled leakage when said disc is abutting said seating means depending on the inlet pressure. ### Claim 19 A valve comprising: an inlet channel and an outlet channel; said outlet channel has an outlet port at a first end, and an aperture at a second end; said inlet channel has an inlet port at a first end, and a second end with an aperture, said aperture being at least part-annularly shaped, wherein said aperture of said inlet channel is concentrically or co-axially arranged surrounding said aperture of said outlet channel; a flow channel is arranged concentrically outside said aperture of said inlet channel, and said flow channel is in fluid communication with said outlet channel; said aperture of said inlet channel and said aperture of said outlet channel are separated by a seating means, and said aperture of said inlet channel and said flow channel are also separated by said seating means; a disc is movably arranged between a closed position abutting said seating means in which fluid communication is prevented between said aperture of said inlet channel and said flow channel and between said aperture of said inlet channel and said aperture of said outlet channel, and an open position in which said aperture of said inlet channel is in fluid communication with both said flow channel and said aperture of said outlet channel; wherein flow through the valve is controlled by an applied force to said disc to close the valve.
