A discharge valve for discharge of pressurized fluid, foam, gel or similar materials includes a sack made out of flexible film material, which is flat welded in a border area in two superimposed layers and a receptacle body, the body being welded in the border area between the two layers of the film material. The valve further includes a valve stem, which is made of an essentially impermeable synthetic material to organic media and has a tubular section, whereby the receptacle body has either a tubular appendage or a corresponding receptacle and the valve stem has either an appendage or receptacle as counterpart for the receptacle body in order to connect the receptacle body and the valve stem with each other using a clamp connection. A gasket arranged between the receptacle body and valve stem at least partially covers the receptacle body on its side facing the valve stem.
