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 end comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is releasably attached to a connect plate. Each connect plate is attached to a power source using a plurality of stay rods. Each fluid end section comprises a housing in fluid communication with a pair of intake manifolds and a discharge conduit. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing. A plunger is installed within stuffing box attached to each housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear.
