A wear-resistant hydraulic fracturing pump valve seat including a body of the valve seat extending radially away from a central axis. The valve seat includes a first top surface configured to form a metal seal with a first bottom surface of a valve head, the first bottom surface positioned closest to a base of the valve head. The valve seat further includes a valve seat step positioned directly adjacent and above the first top surface and a second top surface disposed directly adjacent to and above the valve seat step. The second top surface is configured to form a second metal seal with a second bottom surface of the valve head. The valve seat step is configured to place the first top surface and the second top surface in different parallel planes from each other.

Wear-resistant hydraulic fracturing pump valves

A valve seat for a valve assembly for a high-pressure fluid pump is disclosed. The valve assembly includes a valve body, and a valve seat fabricated of a first material. The valve seat has a generally a tubular body having an annular collar having an outer diameter surface extending beyond the outer diameter surface of the tubular body, and an annular insert fabricated of a second material more durable than the first material and affixed to form an inner diameter surface of the collar, the insert forming an annular sealing surface against which the valve body abuts when in a closed position. The insert forms an annular ledge edge at its inner diameter surface that is offset from the inner diameter surface of the tubular body to form an annular chamfered edge.

Valve seat with ceramic insert

A packing assembly providing a seal point configurable at multiple locations. The packing assembly includes a soft bed having at least one energizing ring and at least one seal ring. The assembly includes a spacer ring sealable with the at least one energizing ring. The assembly further includes at 1=least one adapter ring abutting either end of the soft bed to provide two seal locations relative to the spacer ring.

Moveable seal point packing system

The present disclosure relates, to a wear-resistant hydraulic fracturing pump valve for use in a valve housing, the wear-resistant hydraulic fracturing pump valve comprising: (a) a valve head extending radially from a central axis, the valve head comprising: (i) a first bottom surface comprising a metal and positioned closest to a base of the valve head, wherein the first bottom surface is configured to form a metal seal with a top surface of a valve seat; and (ii) a first annular groove positioned directly adjacent and above the first bottom surface; and (b) a first wear-resistant pump valve gasket configured to mount inside the first annular groove and to form a valve gasket seal with the top surface of the valve seat.

A valve member for an inlet or outlet valve assembly of a reciprocating pump assembly includes a valve body and a seal member. The valve body comprises a first body surface and a second body surface that extend circumferentially about the valve body. The valve body defines a body axis and an annular cavity. The seal member is positioned at least partially within the annular cavity of the valve body such that an outer seal portion of the seal member extends between the first body surface and the second body surface of the valve body. The outer seal portion of the seal member comprises a first seal surface and a second seal surface. The first body surface, the first seal surface, and the second seal surface extend at different angles relative to the body axis.
