Patent number: 10494898Abstract: A flow system for use at a hydraulic fracturing well site, including a tree attached to a wellhead, an inlet head in fluid communication with at least one hydraulic fracturing pump at the well site, and an adjustable fluid conduit providing fluid communication between the inlet head and the tree. The flow system further includes a valve in the fluid conduit and having an open position and a closed position, the valve permitting fluid flow through the fluid conduit when in the open position, and preventing fluid flow through the fluid conduit when in the closed position, at least a portion of the fluid conduit positioned between the valve and the tree.Type: GrantFiled: November 4, 2016Date of Patent: December 3, 2019Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Saurabh Kajaria, Lloyd Ray Cheatham

Patent number: 10196874Abstract: A bonnet assembly for assisting to move a valve stem to a retracted position includes a bonnet body. The bonnet body has a bonnet valve end selectively connected to a valve, a bonnet actuator end opposite the bonnet valve end selectively connected to a valve actuator. A valve stem extends through the central bore of the bonnet body. A booster piston seal circumscribes the valve stem and engages an inner diameter of the central bore. The booster piston seal selectively defines an extent of a pressure cavity containing pressure media. An effective stem pressure surface faces in a direction towards the valve and is in fluid communication with the valve when the bonnet body is connected to the valve. A booster pressure surface faces in a direction towards the valve when the bonnet body is connected to the valve and is selectively acted on by the pressure media.Type: GrantFiled: October 8, 2015Date of Patent: February 5, 2019Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Samuel Heung Yeung Cheng, Keith Adams, Lloyd Ray Cheatham, Travis Kyle McEvoy

Patent number: 10072682Abstract: An apparatus for actuating a valve includes a first actuator having a first actuator housing and second actuator with a second actuator housing. A first plate is positioned within the first actuator housing and a second plate is positioned within the second actuator housing. An intermediate stem extends from a first pressure chamber of the first actuator housing to the second plate. A pressure media path extends through the intermediate stem and a second seal nut that extends into the second plate, the pressure media path providing fluid communication between the first pressure chamber, and a second pressure chamber of the second actuator housing. An injection port is open into one of the first pressure chamber and the second pressure chamber. The first plate and the second plate are movable in response to pressure media injected into the injection port, for actuating the valve.Type: GrantFiled: July 7, 2015Date of Patent: September 11, 2018Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Travis Kyle McEvoy, Keith M.

Patent number: 9909386Abstract: An apparatus for directing a fluid from an inlet to one of a plurality of outlets that are associated with a wellhead assembly includes a block body having a block inlet and a plurality of block outlets. A selector plug is located within the block body, the selector plug having a plug inlet aligned with the block inlet along a central axis, a plug outlet at an angle relative to the central axis, and a plug bore extending from the plug inlet to the plug outlet. A stem member is moveable to selectively rotate the selector plug within the block body so that the plug outlet aligns with one of the plurality of block outlets, providing a fluid flow path from the block inlet to such one of the plurality of block outlets, and impeding fluid communication from the block inlet to the others of the plurality of block outlets.Type: GrantFiled: March 17, 2015Date of Patent: March 6, 2018Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Travis Kyle McEvoy, Lloyd Ray Cheatham, Ben Calvin Holgate, Christopher Dibernardo

Patent number: 9790765Abstract: An apparatus for sealing at least one hub bore of a multi-bore fluid hub associated with a wellhead assembly includes a plug body having a plug bore opening on an outer mating surface. A plug bore extends from a first end of the plug body to the plug bore opening. The plug body is selectively insertable into a hub housing of the multi-bore fluid hub. An insert is in engagement with the outer mating surface and is moveable relative to the plug body between an unengaged position, and an engaged position where the insert seals across one of the hub bores. A stem member is coupled to the plug body and is moveable to selectively rotate the plug body within the multi-bore fluid hub so that the plug bore opening aligns with one of the hub bores and the insert aligns with another of the hub bores.Type: GrantFiled: October 6, 2014Date of Patent: October 17, 2017Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Lloyd Ray Cheatham, Ben Calvin Holgate, Travis Kyle McEvoy, Christopher Michael Menard, Christopher Joseph Dibernardo

Patent number: 9395002Abstract: A gate valve includes a body with a flow passage intersected by a gate cavity and a gate with an axis, the gate being axially movable in the gate cavity between a gate closed position and a gate open position. A lifting device is in engagement with a stem of the gate to move the gate to the gate open position. A port extends from a first external surface of the gate to a second external surface of the gate. A seal member is mechanically connected to the lifting device, the seal member being moveable in response to axial movement of the lifting device between a seal open position where fluids can flow through the port and a seal closed position where the seal member blocks fluids from flowing through the port.Type: GrantFiled: September 24, 2013Date of Patent: July 19, 2016Assignee: GE Oil & Gas Pressure Control LPInventors: Travis Kyle McEvoy, David Daniel Comeaux, Lloyd Ray Cheatham, Edward York
