Abstract: A fluid end is formed from a first body attached to a separate second body. Each body includes an external surface. When the bodies are attached, their respective external surfaces are in flush engagement. A plurality of bores are formed in the second body that are alignable with a plurality of corresponding bores formed in the first body. The fluid end may be used with seals disposed within recesses within each bore to seal against corresponding sealing surfaces. Further, retaining closures may be bolted to the fluid end bodies, such that the closures have a threadless connection to the fluid end bodies. Various combinations of such components may be utilized.

Abstract: A plug valve having an improved sealing assembly. The valve has a body, and a bore formed in the body. The bore is configured to receive a plug and an insert. Recesses are formed in the valve in the internally disposed surface of the bore for placement of seals, which interact with an externally disposed sealing surface of the insert. The plug and insert have complementary surfaces that prevent fluid from passing through the annulus between the plug and insert.
