摘要:
A control valve includes a valve body, a valve seat, and a valve closure member displaceable a closed position and an open position. An attenuation element is provided and includes a plurality of hollow tubes including a first tube, a second tube and a third tube. Each tube includes a flow axis from an open first end to an open second end, and an inner surface defining a flow area and having a cross-sectional shape normal to the flow axis. A second end of the tubes is between the valve closure member and first ends of the tubes along their respective flow axes when the valve closure member is closed. The first tube, the second tube, and the third tube are integrally formed as a single, unitary structure.
