ABSTRACT:
An attenuator valve is provided by utilizing a closure member having a fluid passage therethrough and an attenuator device disposed in the passage of the closure member which protrudes therefrom and which provides a variable degree of attenuation dependent upon the degree to which the valve is opened. The degree of attenuation is proportional to the degree to which the valve is opened. The closure member in combination with the attenuator device provides an optimal attenuation in the full range of valve settings with decreasing attenuation as the valve is opened, and so that at full open position the attenuator device does not significantly restrict the flow of fluid.
