The valve arrangement comprises a valve plate (1) which is connected to the pressure vessel and has a central passage channel (5), in which a valve body (9) is inserted. By deformation in the axial direction, the valve body (9) is raised from a sealing surface (8) of the channel (5) and a passage is created from the interior of the pressure vessel via an outlet borehole (16) into the atmosphere. Filling openings (17) are provided for filling the pressure vessel, which are separated from the outlet borehole (16) by sealing lips (18) which allow passage on one side. The medium introduced at high pressure by means of a filling attachment (28) passes through the filling openings (17) and deforms the sealing lips (18), so that the filling medium can enter the pressure vessel without a substantial part of the filling medium having to pass the small outlet borehole (16). When the filling attachment (28) has been removed, the lips (18) seal off the access to the filling openings (17), so that, when the product stored in the pressure vessel is removed, said product can only escape through the calibrated outlet borehole (16). Thus a pressure vessel, for example an aerosol can, can be filled very quickly without the calibrated outlet borehole being subjected to the risk of damage due to the high filling pressures. <IMAGE>
