  • Publication number: 20240167576
    Abstract: A valve assembly comprising a valve body, a valve housing, and a spring member coupling the valve body to the valve housing. The spring member is configured to align the contact surface of the valve body with the valve seat inside the valve housing. The spring member can be located on the discharge side of the valve body. The valve assembly may be disposed in a fluid end of a positive displacement pump that is operated to flow a wellbore servicing fluid into a wellbore.

  • Publication number: 20210254735
    Abstract: A valve assembly including: a hardened insert coupled with a hardened insert carrier; and a valve body coupled with a valve insert, wherein, in a closed configuration of the valve assembly, the valve body contacts a primary sealing surface of the hardened insert and the valve insert contacts an initial sealing surface of a hardened insert carrier to prevent fluid flow through the valve assembly, and, in an open configuration of the valve assembly, the valve body does not contact the primary sealing surface of the hardened insert and the valve insert does not contact the initial sealing surface of the hardened insert carrier to allow fluid flow through the valve assembly, wherein the hardened insert carrier comprises a reciprocating element, a replaceable valve carrier (RVC), or a pump fluid end body.

  • Publication number: 20200362856
    Abstract: A clamp comprising a first contact surface perpendicular to a central axis of the clamp and a second contact surface tapered relative to a central axis of the clamp, whereby the clamp allows for concentric or non-concentric mating between a first component and a second component such that, when rigidly held together by the clamp such that the first contact surface of the clamp contacts a portion of the first component and the second contact surface of the clamp contacts a portion of the second component, a central axis of the first component is parallel to or coincident with a central axis of the second component.
