A valve insert for a pressurized fluid container has a valve plate deep drawn from sheet metal, a valve body with a central tube that is molded around partial regions of the valve plate, a valve piston guided in the valve body and a valve spring attached to the valve body and acting on the valve piston. The valve plate has one end region with a bell-shaped edge shoulder connected to a flanged edge of the container, another end region with a flanged edge anchored to the central tube of the valve body and a middle region with a beading with a pitch running at least partially around it.
