  • High temperature valve
    Patent number: 4079747
    Abstract: A valve for use with high temperature abrasive fluids includes a valve body having an outer shell of metal, such as low carbon steel, a refractory liner attached to the shell comprising an insulating outer layer of relatively low density castable refractory material, such as alumina, an inner layer of relatively high density castable refractory abrasion resistant material attached to an inner surface of the insulating layer, and a flame sprayed ceramic coating applied to an inner surface of the abrasion resistant castable refractory layer defining a flow passage in the valve body for the passage of fluids. The valve body includes a removable core assembly containing the working parts of the valve.
