Abstract
Valve body insert apparatus and related methods are described. An example valve includes a valve body made of a first material and having a fluid flow passageway and a first shaft bore. The fluid flow passageway defines a first axis and the first shaft bore defines a second axis that is substantially non-parallel relative to the first axis of the fluid flow passageway. A first insert is positioned in the first shaft bore. The first insert is made of a second material different than the first material such that the second material has a higher corrosion resistance characteristic than the first material.
