<p>Valve for regulating and measuring the flow rate of a fluid flowing through a header (1) and a branching duct (2) inside the said header, which comprises means (100;2100) for intercepting the fluid flow, which are movable axially upon operation of associated actuating means (210;2210) integral with an instrument (200) for measuring the flow rate of the fluid flow and comprising an element (202) movable axially against the opposing action of resilient means (204), said means (100;2100) for intercepting the fluid flow being coaxially coupled to a device (300;2300) for regulating the flow rate of the fluid flow which can be rotationally actuated independently of the said fluid intercepting means (100;2100) and is able to maintain its position upon a variation in the axial position of the means (100;2100) for intercepting the fluid flow.</p> |
