| 20110266482 | Floating Ball Valve Seal With Dynamic C-Seal and Static C-Seal - A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exists between the seal ring and the seal carrier and a secondary leak path may exists between the seal carrier and the valve body. A first and second auxiliary seal may prevent fluid flow through the primary and secondary leak path, respectively. | 11-03-2011 |
| 20110266484 | Floating Ball Valve Seal With Bellows and C-Seal - A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exist between the seal ring and the seal carrier and a secondary leak path may exist between the seal carrier and the valve body. A bellows seal may prevent fluid flow through the primary leak path, and an auxiliary seal may prevent fluid flow through the secondary leak path. | 11-03-2011 |

| 20100187462 | AXIAL FLOW CONTROL VALVES HAVING AN INTERNAL ACTUATOR - Axial flow control valves are described herein. An example axial flow control valve described herein includes a valve body defining a passageway between an inlet and an outlet that is substantially parallel to a fluid flow path at the inlet and the outlet of the valve body. The example control valve includes a cartridge assembly removably coupled to the valve body and disposed within the passageway of the valve body between the inlet and the outlet. The cartridge assembly is substantially axially aligned with the passageway and includes a motor to operate the axial flow control valve between a first position to prevent the flow of fluid between the inlet and the outlet and a second position to allow the flow of fluid between the inlet and the outlet. | 07-29-2010 |

| 20090020720 | METHODS AND APPARATUS TO ALIGN A SEAT RING IN A VALVE - Methods and apparatus to align a seat ring in a valve are described. An example fluid valve includes a valve body having a curved internal surface to receive a seat ring and a seat ring having a sealing surface to receive a movable control member and a curved surface opposite the sealing surface to engage the curved internal surface of the valve body. | 01-22-2009 |
| 20090078894 | APPARATUS AND METHODS FOR MANUAL OVERRIDE OPERATION OF A LINEAR ACTUATOR - Apparatus and methods for manual override operation of a linear actuator are described. An example apparatus includes a base to be mounted to an actuator. A drive member is operatively coupled to the base and selectively engagable to a stem of the actuator to enable manual operation of the actuator in a first direction and a second direction. | 03-26-2009 |
| 20090146096 | APPARATUS AND METHODS TO ALIGN A CLOSURE MEMBER AND A VALVE STEM - Apparatus to align a closure member and valve stem for use with valves are described. An example valve includes a stem and a closure member having a first aperture to receive at least a portion of the stem. The example valve further includes a positioning member that has a first portion and a second portion. The first portion has a first cross-section and the second portion has a second cross-section that is greater than the first cross-section and an area between the first portion and the second portion forms a positioning surface to engage the first aperture of the closure member to align the stem and the closure member. A fastening member couples the stem to the closure member. | 06-11-2009 |
| 20110204275 | METHODS AND APPARATUS TO ALIGN A SEAT RING IN A VALVE - Methods and apparatus to align a seat ring in a valve are described. An example fluid valve includes a valve body having a curved internal surface to receive a seat ring and a seat ring having a sealing surface to receive a movable control member and a curved surface opposite the sealing surface to engage the curved internal surface of the valve body. | 08-25-2011 |
