  • Patent number: 12110979
    Abstract: A gate valve body having a gate cavity intersecting a channel having a proximal channel portion and a distal channel portion on opposing sides of the gate cavity, a gate positioned in the gate cavity and moveable between closed and open positions, the gate having a proximal gate face and a distal gate face extending perpendicular to the channel; a proximal seat between a proximal valve body portion and the gate, the proximal seat having a first proximal seat face adjacent a proximal valve body face and a second proximal seat face adjacent the proximal gate face; a proximal annular groove on a radial outer surface of the proximal seat; a proximal axial seal positioned in the proximal annular groove in contact with the proximal seat and the valve body; and a proximal conduit extending through the proximal seat between the proximal channel portion and the proximal annular groove.

  • Patent number: 12060759
    Abstract: An internal locking ring assembly for a wellhead system that includes a compact single body locking ring design that eliminates the need for a separate casing head and housing configuration or the use of numerous lockdown pins, therefore increasing the safety of the entire drilling operation. The internal locking ring includes outer and inner diameter grooves and angles to accommodate a running tool for collapsing the locking ring for positing into wellhead seats all at lower forces than what is typical due to the lower retrieving torque when trying to retrieve the packoff. Such lower retrieving torque and force allows the use of smaller cross sections of a running tool.

  • Patent number: 11698138
    Abstract: An exemplary gate valve includes a valve body having a gate cavity intersecting a through bore, the gate cavity extending through a first end of the valve body, an inner surface forming the gate cavity is angled outward from a center axis of the gate cavity to a gate cavity opening at the first end, and a gate positioned in the gate cavity and moveable between a closed position blocking flow through the through bore and an open position allowing flow through the through bore, the gate having a sealing face extending perpendicular to the through bore.

  • Patent number: 9091351
    Abstract: A gate valve system for controlling fluid flow having a valve body with a bore through which fluid can flow. The system includes a valve body having a bore to allow fluid to pass through the valve body and further having a cavity defined by substantially parallel innerside walls of the valve body, a gate wherein at least one end of the gate is defined by a radius perimeter. The system also has a bonnet that is removably coupled to a face of the valve body, wherein a portion of an innerside of the bonnet includes a curved surface adapted to mate with the at least one end of the gate defined by the radius perimeter, and an actuation mechanism operationally positioned and removably connected to the gate by way of a thru-hole in the bonnet.
