ABSTRACT:
An attenuator valve assembly includes a closure member having one or more attenuator plates associated with it. The closure member have the form of a ball with a bore, a ball calotte, or a butterfly valve disc, etc. The attenuating effect of the attenuator plates are called into play immediately when the closure member is first opened, with the attenuating effect greatest during initial opening of the closure member and diminishing as the closure member is moved toward the completely open position. When the closure member is in the form of a valve disc or ball calotte, the attenuator plates are mounted for rotation with the closure member spaced from the closure member.
