Abstract: A valve seat. The valve seat is used in a fluid end of a fracturing pump. The external surface of the valve seat has a tapered portion that retains the valve seat in the fluid end. The external surface also has a portion that is substantially cylindrical. A hardened insert is integrated into a strike face of the valve seat. The tapered portion is at a first end of the valve seat and the tapered portion is at a second end of the valve seat. The second end of the valve seat may be formed such that its exterior surface does not contact the fluid end.

Abstract: A check valve with a flapper for directing high pressure abrasive fluid away from its sealing face. The check valve has a flapper which opens when fluid travels from an inlet to an outlet. The flapper closes when fluid flow stops or reverses by sealing a flat sealing face to a seal formed in a shoulder face of the valve. A surface feature protrudes from near the flat sealing face and forms a slanted face opposed to the direction of flow through the valve. This slanted face interfaces with fluid flow to more easily open the valve and directs flow away from the sealing face to reduce wear.

Abstract: A pair of wear grooves for a linear drive assembly. One wear groove is disposed on a wear plate attached to a crosshead. This wear groove is on a front edge of the wear plate, and does not intersect any lubrication groove. Another wear groove is disposed circumferentially about an inner wall of a crosshead guide. Each of the wear grooves is observable to an operator without fully disassembling the crosshead and the crosshead guide, and each is observable from a single side of the crosshead guide. Should the wear groove not be observable, the associated component should be replaced. Should the wear groove be observable, the remaining life of the component can be determined from the groove's depth.

Abstract: A manifold assembly configured for use with a fluid end used in oil and gas operations. The manifold assembly comprises upper and lower manifolds supported on side posts such that the manifolds and posts define a central opening. In operation, the fluid end is positioned within the central opening such that the manifold assembly surrounds the fluid end. The manifold assembly is not attached to the fluid end other than flexible conduits interconnecting the fluid and the manifolds. The manifold assembly is modular and when assembled, may be moved together as a single unit.
