    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 end section having a clamping system. The clamping system has a primary clamp formed of a number of sections, which, disposed in end-to-end arrangement, form an annular ring. The primary clamp has an angled surface at each of two rims, which interact with complementary surfaces on flanges that form two separate components of the fluid end section. Each of the two separate components have a bore, which when aligned by placement of the clamp, are in alignment with one another. The clamp has an externally-disposed compression ring, which may either be essentially the width of the primary clamp, or may have one or more flexible rods which interact with grooves on the primary clamp. In either case, the compression ring holds the primary clamp in place, therefore joining the components of the fluid end.
