Abstract

A ball and seat valve for high temperature and pressure applications, such as those used in isolation barrier valves in subterranean wells, is disclosed. The valve incorporates thermally fitted sleeve into the ball and/or the seat to allow for greater pressures and temperatures due to resultant stresses left with the parts due to interference. Additionally, the materials making up the sleeves may be chosen to allow for greater resistance to corrosive and erosive wellbore fluids.
