Abstract: 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.

Abstract: 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.
