AI Technical Summary
Technical Problem
Self-actuated valves face challenges when operating in environments involving high-solids concentration slurries, particularly due to abrasive wear and the risk of valve stem failure from shear stress.
Method used
The valve body design includes a central valve body portion with a valve seat engagement surface, a support surface, and a valve stem, along with an annular support that provides additional stress relief and support to the valve stem, reducing the risk of fatigue and shear failure.
Benefits of technology
The design enhances the structural integrity and durability of the valve stem, reducing the risk of premature failure and improving the valve's ability to operate effectively in challenging slurry environments.

Abstract
A valve body defining a longitudinal axis and comprising: (i) a central valve body portion comprising: (a) a valve seat engagement surface, (b) a support surface extending from the valve seat engagement surface, and (c) a valve stem extending from the support surface along the longitudinal axis; and (ii) an annular support mounted on the support surface around the valve stem and defining: (a) a stem aperture through which an upper portion of the valve stem extends, (b) an upper cap portion and (c) a frusto-conical portion extending from the valve seat engagement surface to the upper cap portion.
