La bola y el asiento de la válvula de aleación de cromo cobalto son partes muy importantes de la bomba de pozo de petróleo, siempre aparecen juntas y cooperan muy bien, ahora no hay mejor material que pueda reemplazarlas.
Las bolas de la válvula están hechas de Cobalt Chrome Alloy 20 y el asiento de Cobalt Chrome Alloy están hechas de Cobalt Chrome Alloy 3. Son un buen equipo para resistir el problema del desgaste y la corrosión en el proceso de proxenetismo de petróleo y gas.
