The valve assembly for use with high temperature and high pressure fluids has inner and outer spaced shells and a valve actuator support of inner and outer spaced members which are connected at their end portions to the inner and outer shells, respectively, to extend substantially normal to the longitudinal axis of the inner shell. A layer of resilient heat insulating material covers the outer surfaces of the inner shell and the inner actuator support member and is of a thickness to only occupy part of the spaces between the inner and outer shells and inner and outer actuator support members. The remaining portion of the space between the inner and outer shells and the space between the inner and outer members is substantially filled with a body of castable, rigid refractory material. A movable valve member is disposed in the inner shell. A valve actuator assembly is supported in the valve actuator support to extend into the inner shell for connection with the movable valve member for movement of the movable valve member to positions from a fully open to a fully closed position to control flow of fluid through the inner shell. An anchor mneans is disposed adjacent opposite sides of the axis of the valve actuator support and attached to the inner shell so that relative radial movement between the inner and outer shell is permitted by the layer of resilient heat insulating material and relative longitudinal movement of the inner shell to the outer shell is permitted in opposite directions from the anchor means to thereby maintain the functional integrity of the movable valve member by providing an area of the inner shell surrounding the movable valve member longitdinally stationary, but at the same time allowing radial movement.

A valve assembly capable of use with fluids of high temperature and pressure comprising: a. inner and outer shells diametrically sized to form a first space therebetween; b. a valve actuator support having coaxially disposed inner and outer tubular members diametrically sized to define a second space therebetween communicating with said first space. c. said inner tubular member has two telescopically arranged portions, one portion being secured to the outer shell while the other portion is secured to the inner shell; d. a layer of resilient insulating material covering substantially all of the outer surfaces of said inner shell and of said inner tubular member of said valve actuator support and of a thickness to occupy part of the first and second spaces; uator means for movement to positions from a fully open to a fully closed position to thereby control fluid flow through said inner shell; h. anchor means connected to said inner shell adjacent said movable valve member for securing said inner shell in the area of the movable valve against longitudinal movement relative to the outer shell and refractory body while not preventing radial movement of said inner shell relative to the outer shell and refractory body; and i. connecting means at opposite ends of the inner and outer shell for connecting said shells to fluid conducting elements.
