A B S T R A C T A valve 1 for controlling a fluid medium flowing under pressure comprises an inlet opening 6 and an outlet opening 12 as well as an inlet member 4 having the medium flowing axially therethrough and a sleeve-shaped control member 13 axially displaceable between a closed and an open position relative to the inlet member 4, whereby in the closed position the outlet opening 12 is closed and in the open position the outlet opening 12 is opened. In addition, a first radially projecting, elastic sealing ring 24b is provided and a first annular sealing edge 25 which is adapted to be pressed sealingly against the first sealing ring 24b in a closed position of the control member 13. The displaceable control member 13 is enclosed by a valve housing 2 and the space between control member 13 and valve housing 2 is acted upon by the fluid medium flowing under pressure so that essentially no resulting pressure in axial direction is present at the control member and therefore the control member 13 is displaceable without any appreciable expenditure of force. A second radially projecting, elastic sealing ring 26b is provided in axial spaced relation to the first sealing ring 24b. A second annular sealing edge 27 is adapted to be pressed sealingly against the second sealing ring 26b in a closed position of the control member 13.
