摘要： A hydraulic valve seat release system for a fluid end of a high pressure pump, comprised of method and apparatus for releasing a valve seat having a tapered outer diameter for sealingly mating when installed in the tapered interior of a fluid end suction or discharge bore via interference fit. The fluid end module of the invention includes internal high pressure porting between an exterior surface of the fluid end module and the interior surface of the bore, whereby high pressure fluid may be applied to the tapered surface of the bore and into a fluid channel around the circumference of the tapered outer diameter of the valve seat. The high pressure fluid compresses the outer diameter of the valve seat and expands the interior diameter of the bore in order to disrupt the interference fit between the valve seat and the bore thereby releasing the valve seat.
