Abstract: A valve having a nose joined to a strike face. The strike face is configured to engage a tapered sealing surface formed on a component having a central fluid bore. The valve and component are configured to be installed within a fluid end. When the strike face of the valve engages the tapered sealing surface of the component, the nose is installed within the central fluid bore of the component. In operation, fluid is restricted from flowing between the strike face and the tapered sealing surface until fluid pressure has pushed the nose entirely out of the central fluid bore, thereby increasing the cross-sectional area available for fluid flow.

Abstract: A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.
