Valve for regulating and measuring the flow rate of a fluid through a header (1) and a branch duct (2,2b) inside the said header, which comprises means (10,10a) for shutting off the aperture (2b) of the branch duct (2), which are movable axially upon operation of associated actuating means (30), means (44) for detecting the pressure exerted by the fluid flow, an instrument (43,43a) for measuring the flow rate of the fluid, the scale (43a) of which is shown on the external surface of said actuating means (30), said means (10,10a) for shutting off the aperture (2b) of the branch duct (2) being connected to the said actuating means (30) so that a rotation of the latter results solely in an axial movement of the former and the shut-off means (10,10a) are independent of the measuring instrument (43,43a) during their movement in an axial direction. <IMAGE>
