    Abstract: A flow restrictor is provided for a plug valve. The flow restrictor includes a restrictor body configured to be at least one of held within an internal bore of a valve body of the plug valve or mounted to the valve body in fluid communication with the internal bore. The restrictor body includes a plurality of fluid passages extending through a length of the restrictor body. The fluid passages include turns such that the fluid passages define tortuous fluid paths through the restrictor body.

    Abstract: A valve assembly for use in a fracturing pump including a valve member movable into and out of engagement with a valve seat body. The valve seat body includes an outer surface and an inner surface, the inner surface forming a fluid bore extending between a first end and a second end of the valve seat body. The body further includes a seating surface extending radially from the inner surface and facing the valve member, the seating surface having a recessed area. An insert is disposed in the recessed area forming at least a portion of the inner surface and at least portion of the seating surface. The valve seat body first end has a diameter different from a diameter valve seat body second. The difference between diameters allows the valve seat body outer surface to be supported by the fluid passageway.

    Abstract: An apparatus is adapted to be coupled to a component of a system associated with a wellhead. The apparatus includes a band adapted to be coupled to the component; a holder coupled to the band; an electronic identifying device attached to the holder and adapted to identify the component; and an identifying component coupled to the band. The identifying component visually conveys information about at least one of: the electronic identifying device, and the component to which the band is adapted to be coupled. The system associated with the wellhead is a system for pumping fluid to the wellhead. In one embodiment, the electronic identifying device is, or includes, an RFID chip.

    Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to sliding surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of rolling surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.

    Abstract: A fluid end block for attachment to a power end of a high pressure reciprocating pump includes a main body portion having an outwardly facing body forward face, an outwardly facing body rear face opposite the body forward face, and opposing side surfaces. A web portion protrudes outwardly from the outwardly facing body forward face. The web portion may have an outwardly facing web forward face and a curvilinear side surface. The web portion may be integral with the main body portion. A plurality of bosses protrude from the web forward face and having a forward facing end. The plurality of bosses may be integral with the main body portion and the web portion. A plunger bore extends through one of the plurality of bosses configured to receive a reciprocating plunger.
