ROBINET A DIAPHRAGME A COMMANDE ELECTROMECANIQUE, EN PARTICULIER POUR LE RACCORDEMENT DE CONDUITES DE FLUIDE D'ARROSAGE ET/OU LES SYSTEMES D'HERBICIDES ET PRODUITS SIMILAIRES
An electromechanically actuated membrane valve, particularlybranching ducts of a fluid of sprinkling and/or weed control systems and thelike, comprising a hollow valve body which can be associated with an endportion of a branching duct of a fluid or the like and contains inside it apiston adapted to interact with a disk-like membrane for blocking the endportion of the branching duct.In more detail, the piston is movable with respect to the valve bodybetween an open configuration and a closed configuration of the valve andthe branching duct comprises an internal duct and an external duct whichare mutually coaxial.The peculiarity of the invention consists in that it comprises meansfor reducing the passage section of the internal duct, which are associatedwith the valve body and adapted to interact with the disk-like membrane onthe side opposite to the piston for the hermetic isolation of the internalductwith respect to the external duct and vice versa.
