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.
