Abstract: A valve assembly includes a valve body, having an inlet duct, an outlet duct and an intermediate portion. An electrovalve is located proximal to the intermediate portion. A measurement device is directly connected to the valve body. The measurement device includes a sensor for taking a measurement for determining a physical characteristic of the fluid that can flow in the valve assembly. The electrovalve includes a first electronic circuit for conducting an electric control signal from a control unit to the electrovalve. The measurement device includes a second electronic circuit for conducting the electric signals exchanged between the control unit and the sensor. The first electronic circuit and the second electronic circuit are implemented on a single header or printed circuit board. The electrovalve and the measurement device are mechanically connected directly to the single header or printed circuit board.

Abstract: A device for measuring the flow rate of a fluid, including a bladed impeller mounted in the conduit to be driven in rotation by the flow of the fluid, and to which at least one magnet is fixed, and a magnetic field sensor arranged near the conduit to generate a signal each time the magnet of the impeller, passes thereby. The number of signals generated by the sensor in a period of time is representative of the flow rate of the fluid.

Abstract: A valve device (10) includes a hollow body (12) adapted to be passed through by a flow of fluid and having an inlet section (12a) and at least one outlet section (12b) to receive and dispense fluid. A joining element (14) connects to a fluid source, and connects at the inlet section (12a). A support bracket (16) is assembled to the inlet section (12a) to hold the joining element (14) connected to the hollow body (12), and is configured to be fastened to an external load-bearing structure. One electrically controlled valve (18) is arranged in the hollow body (12) between the inlet section (12a) and the outlet section (12b), and configured for selectively controlling the exit of the flow of fluid.

Abstract: The regulating device (1) comprises a body (2) including a hub (3) which has a first end (3a) connected to a surrounding ring (4), such as to define therebetween at least one passage (6) for the fluid, between the upstream and downstream regions, and the other or second end (3b) of which protrudes with respect to the ring (4). The ring (4) has, on a surface thereof, an annular distribution of projections (7). On the second end (3b) of the hub (3) there is mounted a flexible, ring-shaped, regulating member (8) facing and spaced from the tops of said projections (7) and capable during use of resiliently flexing towards them as a result of and depending on the difference in pressure between the upstream and downstream regions. The ring (4) is further provided with a plurality of restricted holes (10) having a fluid flow parallel to the at least one passage (6).
