Abstract
A valve assembly for a fracturing pump includes a valve seat having a bore extending therethrough, the valve seat including a strike face at a top region opposite a bottom region, at least a portion of the strike face formed by an insert positioned within a groove formed in the valve body. The valve assembly also includes a bore liner arranged within the bore, at least a portion of an axial length of the bore liner covering at least a portion of the ceramic to form a barrier between the insert and the bore. The valve assembly further includes a valve member positioned to reciprocate within the bore, the valve member moving between an open position and a closed position, wherein at least a portion of the valve member engages at least a portion of the strike face in the closed position.
