A valve for filling liquids into packages has a housing (1) with a supply connection piece (24), a forward mouth piece and an outlet device (16) in which a large number of outlet holes (4) is arranged. A closing member (3) is movably arranged in the housing (1), and can be engaged with a valve seat (23). Rear sealing devices (5, 7, 22) are also provided. In order to make possible a high volume flow of the liquid contents at low outlet speed without relative movement occurring between the package and outlet device (16) it is provided that the outlet holes (4) distributed over the whole cross-section of the mouth piece (2) are arranged in an outlet plate (16) which is configured integrally with the mouthpiece, and penetrate it in the direction (26) of the longitudinal axis (28) of the mouth piece, that the diameter and the width of the outlet holes (4) is larger than 1 mm and smaller than 5 mm, and that the length of the outlet holes (4) is greater than double their diameter and their width.
A valve for filling liquids into packages, with a housing with a supply connection piece at a rear of the housing, a forward mouth piece and an outlet device in which a large number of outlet holes is arranged, with a closing member movably arranged in the housing which can be engaged with the valve seating and with sealing devices arranged at the rears whereby the outlet holes are distributed over the whole cross-section of the mouth piece and are arranged in an outlet plate and penetrate it in the direction of the longitudinal axis of the mouth piece, wherein said outlet plate is configured integrally with the mouth piece such that the mouth piece downstream of a connecting thereof to the housing is shaped integrally as one piece having a continuous surface, and that the diameter and width of the outlet holes is greater than 1 mm and less than 5 mm, and that the length of the outlet holes is greater than twice their diameter or width.
