Abstract
A Two-way valve for regulating and measuring the flow rate of a fluid through a header (1) and a branched duct (2,2a) inside the header itself. The valve (10a, 10, 11, 11c) which shuts off the aperture (2b) of the branched duct (2) is internally hollow and movable axially by an associated actuator (13). Discs (30, 130) for detecting the pressure exerted by the flow of the fluid are integral with elements (20, 40) movable axially against the opposing action of a spring (60, 160) and form part of an instrument (70, 170) for measuring the flow rate. The valve comprises a head (10a), on the side surface of which recesses (10d) are formed.
