    Abstract: A stem-guided valve for use inside of a fluid end. The valve body is installed in a conduit that traverses the fluid end housing. A removable guide element is installed within a bore formed in the valve body. A static component that is interposed within the conduit includes an elongate projecting stem. As the stem reciprocates axially with the guide element, the valve is caused to move between open and closed positions. In its closed position, the valve body engages a valve seat that surrounds the conduit. A plurality of perforations are formed in the walls of the guide element, the perforations allow fluid to drain from the guide element during operation.

    Abstract: A high pressure swivel joint used in pipe assemblies transferring high pressure fluid. The swivel joint comprises a first pipe section and a sleeve-like second pipe section. The first pipe section is inserted into the second pipe section and the sections are relatively rotatable. A wear ring is positioned within a recess formed in the inner wall of the first pipe section. A second wear ring is positioned within a recess formed in the inner wall of the second pipe section.

    Abstract: A valve for use in a fluid end. The valve has a solid body with a sealing surface. The valve may move into a position wherein the valve when contacts a valve seat. When in contact, the sealing surfaces prevent flow of fluid through the valve. The sealing surface has three regions. The outer region has an elastomeric seal insert disposed on the surface. The inner region has a shock absorbing insert disposed on the surface. Intermediate these inserts is a metallic surface for metal-to-metal sealing with the valve seat.

    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.
