Abstract
A closure member is configured for use in a valve. These configurations may include a plug with grooves or “flutes” that extend along its length. Inserts in the flutes may comprise materials, like ceramics, that are different than the material that forms the core or base portion of the plug. These inserts are useful to slow erosion of the device, particularly in the flutes, which form an outwardly-facing surface that is subject to high velocity flow in the valve. This feature can extend service life of the plug, particularly in highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations.
