Abstract: A multiple nozzle holder assembly with increased operating flexibility, comprising a main body provided with an inlet for a working fluid and with at least two outlets for the fluid, the inlet having a fluid connection to each outlet by means of a respective passage duct that is sectioned by corresponding valve elements for flow control with automatic actuation, an additional body being provided with at least three couplings for connection to respective atomizing nozzles, which is associated with the main body so that it can move among several operating configurations, at least two of which are delivery configurations in which selectively at least two of the at least three couplings each have a fluid connection to one of the at least two outlets.

Abstract: An electromechanically actuated membrane valve, for branching ducts of sprinkling and/or weed control systems, comprising a hollow valve body associated with an end portion of a branching duct of a fluid that contains a piston adapted to interact with a disk-like membrane for blocking the end portion of the branching duct. The piston is movable in the valve body between an open configuration and a closed configuration of the valve. The branching duct comprises an internal duct and an external duct which are mutually coaxial. A passage section reduction element for the internal duct is provided associated with the valve body to interact with the disk-like membrane for the hermetic isolation of the internal duct with respect to the external duct and vice versa.
