Abstract: A multi-piece fluid end that can be produced with fewer raw materials and at a lower cost. In one embodiment, a fluid end is formed from a first body attached to a separate second body. Their respective external surfaces may be engaged flushly, partially, or via one or more spacer elements. In some embodiments, the body pieces are flangeless to reduce stress on the fluid end. The second body may have a plurality of bores that are alignable with a plurality of corresponding bores formed in the first body. The second body may be connected to a power end using a plurality of stay rods. In other implementations, more than two body pieces may be utilized.

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.

Abstract: An apparatus and associated method for operating a machine tool having a selectively movable turret and a tool mounted to the turret. A cover is configured to be removably secured to the turret and sized so that the cover encloses the tool when the cover is secured to the turret. Turret control logic includes computer instructions stored in a computer memory and executable by a computer processor to limit movement of the turret when the cover is secured to the turret.
