Abstract
An edge wear tab for high temperature valve components, such valve components having an upstream face and a downstream face. The edge wear tab of the present invention has an increased mounting area for enhanced ease in mounting the tab body with the valve and for increased anchoring of refractory or composite material with the valve component. Further, the edge wear tab of the present invention enhances valve component strength by increasing localized compressive forces in such refractory or composite materials in the area adjacent to such tab body.
