Abstract
Typically, fluids used in fracking operations erode valve seats in the fluid end of the reciprocating pump. Thus, these valve seats must frequently be replaced by new valve seats. Accordingly, a remanufacturing process is disclosed that successively cleans and/or grinds manually or mechanically at least the carbide inserts from used valve seats until the inserts are reusable. This reduces material costs and promotes efficiency and sustainability.
