A B S T R A C T An aerosol valve has a valve housing (22) provided with a peripheral flange (50) that will yield under pressure and permit the housing and the valve gasket (28) to move away from their sealing relation with the pedestal (14) of the mounting cup closure and to return to said sealing relation upon terminating the filling operation. A series of openings in the flange permit passage of the propellant between the upper surface of the gasket, through the flange and directly into the container (20), without need for the propellant to pass through the more constricting orifices controlling egress from the valve unit internal of the valve housing. A further feature is a filling head which is constructed such that when the filling head (72) is in position for filling with the propellant, the valve body (24) is moved away from the top of the pedestal through engagement of the valve stem with a filling stem actuator (84), or, in the case where a valve actuator is disposed on the valve stem, the valve actuator and a stem actuating member in the filling head.
