A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

Techniques for delivering lubricant to a packing assembly of a fluid end of a reciprocating pump include delivering lubricant to a stuffing box that is housing a packing assembly or to a manifold disposed in or around the stuffing box. The lubricant configured to decrease friction between an interior surface of the packing assembly and a reciprocating component moving along the interior surface. Prior to delivering the lubricant to the interior surface of the packing assembly, the lubricant is diverted to multiple radial flow paths circumferentially spaced around a bore in which the packing assembly is disposed. The multiple radial flow paths lead to the interior surface of the packing assembly and the lubricant flowing through the multiple radial flow paths is metered at different flow rates based on a friction gradient across the interior surface of the packing assembly.

A valve component utilized in a fluid end assembly of a reciprocating pump may contain a multi-piece construction. The valve component may include a valve body portion, a leg assembly portion, a sealing element, and an insert at least partially captured between the valve body portion and the leg assembly portion. The insert may be constructed from a carbide or a ceramic material, and, when the valve component is fully assembled, may be compressed between the valve body portion and the leg assembly portion. The insert may at least partially form the strike surface of the valve component. The valve body portion and the leg assembly portion may both be constructed from a metallic material, and the valve body portion may define a sealing seat. The sealing element may be constructed from an elastomeric material that may be pre-formed and then compression molded onto the seat of the valve body.

A packing arrangement for a fluid end of a reciprocating pump is received within a packing box and is arranged to form a seal with a plunger. The packing arrangement includes a plurality of separate annular rings arranged in an abutting relationship with one another within the packing box, and a header ring disposed within the plurality of separate annular rings, the header ring including an inner surface that is non-cylindrical and that is arranged to abut the plunger, a high pressure side that is arranged in a female chevron shape, and a low pressure side opposite the high pressure side. A packing nut is engaged with the fluid end and operable to compress the header ring and the plurality of separate annular rings within the packing box.
