A valve, in particular for household appliances; the valve comprising: - a valve body having at least one supply duct at least one delivery duct, and a chamber, which extends around a longitudinal axis between the at least one supply duct and the at least one delivery duct - a shutter assembly movable with respect to the valve body along the longitudinal axis between an open position and a closed position to respectively allow and interrupt the flow of a fluid between the at least one supply duct and the at least one delivery duct; - a first rigid tubular body, which extends along the longitudinal axis, is configured to guide the shutter assembly, is at least partially housed within the valve body and comprises one opening extending about the longitudinal axis and a plurality of lateral openings; - a second tubular body, which is coupled to the valve body (2; 42); - a first annular sealing member placed between the shutter assembly and the first tubular body so as to separate a wet area from a dry area along the first tubular body; and wherein the first tubular body is housed in the valve body and is axially clamped between the valve body and the second tubular body, characterized in that the second tubular body is coupled to the valve body by means of a bayonet coupling; and in that the valve further comprises a second annular sealing member housed in the first tubular body and configured to interfere with the shutter assembly so as to interrupt the flow of fluid between the at least one supply duct and the at least one delivery duct, wherein the first annular sealing member and the second annular sealing member are O-rings. - a valve body having at least one supply duct at least one delivery duct, and a chamber, which extends around a longitudinal axis between the at least one supply duct and the at least one delivery duct - a shutter assembly movable with respect to the valve body along the longitudinal axis between an open position and a closed position to respectively allow and interrupt the flow of a fluid between the at least one supply duct and the at least one delivery duct; - a first rigid tubular body, which extends along the longitudinal axis, is configured to guide the shutter assembly, is at least partially housed within the valve body and comprises one opening extending about the longitudinal axis and a plurality of lateral openings; - a second tubular body, which is coupled to the valve body (2; 42); - a first annular sealing member placed between the shutter assembly and the first tubular body so as to separate a wet area from a dry area along the first tubular body; and wherein the first tubular body is housed in the valve body and is axially clamped between the valve body and the second tubular body, characterized in that the second tubular body is coupled to the valve body by means of a bayonet coupling; and in that the valve further comprises a second annular sealing member housed in the first tubular body and configured to interfere with the shutter assembly so as to interrupt the flow of fluid between the at least one supply duct and the at least one delivery duct, wherein the first annular sealing member and the second annular sealing member are O-rings.
