  • Patent number: 4024891
    Abstract: A noise abating plug for a fluid control valve includes a perforated sleeve that forms one end portion of the plug and a plurality of spaced apart perforated discs that extend between a hub portion of the plug and the inner wall of the sleeve portion. The perforations in the sleeve and in the multi-perforated discs form a varying number of restrictive passageways for the fluid under control as the plug is moved between its open and closed positions and thereby maintain the pressure reduction occurring at the perforated sleeve and perforated discs at values which minimize the noise created by the fluid as it flows through the valve.
