Valve device (100, 100" 100") for an acquastop system to be used in a household appliance, such as a dishwasher or a laundry machine; said device comprising: - a hollow body having an inlet portion, which is hydraulically connectable to a water intake to receive a water flow, and an outlet portion, which is hydraulically connectable, in particular by means of a supply tube of said acquastop system surrounded by a safety tube of said acquastop system, to said household appliance so as to deliver said water flow; and - a valve apparatus, which is fixed to said hollow body, arranged between said inlet portion and said outlet portion, and arranged to control the passage of said water flow through said hollow body; said outlet portion has a plurality of outlets (106a, 106b) for a water flow, each one of said outlets (106a, 106b) being able to be connected to a respective duct (12a, 12b) of the supply tube; said hollow body defines a plurality of paths (110a, 110b) for the water, which are separate from one another, each path (110a, 110b) branching off said inlet portion and leading to a corresponding outlet (16a, 16b); and said valve apparatus comprises a plurality of solenoid valves (108a, 108b), each solenoid valve (108a, 108b) being arranged to control the passage of water through a corresponding path (110a, 110b) substantially independently of the other solenoid valves (108a, 108b); said device being characterized in that at least one of said paths (110a, 110b) for the water is defined by a series of channel segments or ducts (122, 124, 126, 128, 130), which extend inside the hollow body, wherein said series comprises: - an axial inlet segment, which branches off said inlet portion and substantially extends parallel to the longitudinal axis (X-X) of said hollow body, - a transverse segment, which transversely deflects from said axial inlet segment, - an annular chamber, to which said transverse segment leads, - a transverse interception passage, which is radially internal relative to said annular chamber and is capable of being obstructed and freed by the respective solenoid valve (108a, 108b), and - an axial outlet segment, which axially deflects relative to said transverse interception passage and leads to the respective outlet (106a, 106b). - a hollow body having an inlet portion, which is hydraulically connectable to a water intake to receive a water flow, and an outlet portion, which is hydraulically connectable, in particular by means of a supply tube of said acquastop system surrounded by a safety tube of said acquastop system, to said household appliance so as to deliver said water flow; and an inlet portion, which is hydraulically connectable to a water intake to receive a water flow, and an outlet portion, which is hydraulically connectable, in particular by means of a supply tube of said acquastop system surrounded by a safety tube of said acquastop system, to said household appliance so as to deliver said water flow; and - a valve apparatus, which is fixed to said hollow body, arranged between said inlet portion and said outlet portion, and arranged to control the passage of said water flow through said hollow body; - an axial inlet segment, which branches off said inlet portion and substantially extends parallel to the longitudinal axis (X-X) of said hollow body, - a transverse segment, which transversely deflects from said axial inlet segment, - an annular chamber, to which said transverse segment leads, - a transverse interception passage, which is radially internal relative to said annular chamber and is capable of being obstructed and freed by the respective solenoid valve (108a, 108b), and - an axial outlet segment, which axially deflects relative to said transverse interception passage and leads to the respective outlet (106a, 106b).
