<p>The invention relates to a valve for a fluid cylinder, a first draw-off circuit (3) comprising a member (4) for regulating the flow and/or pressure of the drawn-off fluid, the valve (1) comprising a manual control member (5) and an electronic device (6) displaying data relating to the fluid contained in a cylinder connected to the valve (1). The electronic display device (6) comprises a data-acquisition, -storage and -processing member (7) and at least one display (8); the valve (1) comprises a sensor (9) detecting the position of the control member (5); and the data-acquisition, -storage and -processing member (7) is designed to control, in response to the receiving of an imposed flow and/or pressure signal, the displaying on the display (8) of information concerning the flow and/or the pressure of the fluid imposed by the regulating member (4) and/or the valve use mode. The sensor (9) for detecting the position of the control member (5) comprises a mechanism (19) which meshes with the control member (5), and a potentiometer (39), the mechanism (19) comprising a mobile part (29), forming a cursor of the potentiometer (39), the position sensor (9) supplying a voltage and/or resistance value determined as a function of the position of the control member (5).</p> |
