Valve for regulating and measuring the flow rate of a fluid through a manifold (1) and a branch pipe (2,2b) inside the said manifold, which comprises flow intercepting means (10,100) movable axially upon operation of associated actuating means (30), means (44) for detecting the pressure exerted by the fluid flow, which are integral with axially movable elements (40) forming part of an instrument (43,43a) for measuring the flow rate of the fluid, said means (10,100) for intercepting the fluid flow being connected to the said actuating means (30) so that a rotation of the latter produces the sole axial movement of the former, wherein the circumferential surface of said intercepting means (100) has at least one slit (110;110,120) for entry of the fluid into the branch pipe (2) in a radial direction and an annular edge (101) extending radially outwards and able to come into contact with the seat (2d) of the valve in order to produce closing of the latter. <IMAGE>
