Abstract
A shut-off valve for high temperature erosive flow is disclosed having a valve and a valve engaging or seating portion in which substantial erosion of an area beginning at its initial erosion point adjacent the valve seat does not erode the valve seating portion of the valve seat and the valve seating portion of the valve member to prevent closing of the valve or to cause leaks. The valve has limited but enough universal movement to be self-seating to accommodate thermal growth. The valve and valve seat can be removed from the valve without taking the valve off the line. A number of embodiments are disclosed.
