Use of expanded metal 6 as a noise-damping member for reducing the noise level in the outlet in for example regulating valves for flow or pressure regulation of gas or steam. The invention is characterized in that at least one layer of expanded metal 6 is arranged between two surfaces 8 bearing against the expanded metal and in that the openings 7 of the expanded metal extend essentially transversely to the direction of flow of the gas or steam through the expanded metal 6 between the surfaces 8. <IMAGE> |
