| 137150220 | Ball valve or rotary ball valve | 7 |
| 20100200078 | METHOD OF ASSEMBLING A BALL VALVE - A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings. | 08-12-2010 |
| 20110265886 | BALL VALVE SEAL ASSEMBLY AND BALL VALVE COMPRISING SAME - A seal assembly in a rotary ball valve is installable and replaceable through a bonnet opening in a valve body of the rotary ball valve. The seal assembly includes an anchor ring located in an internal recess in the valve body and one or more seal assembly components, such as a flexible seal member, a seal carrier, a seal retainer, and a rigid seal ring, are secured to the anchor ring. | 11-03-2011 |

| 20140190575 | VALVE INCLUDING A DEVICE FOR IMMOBILIZING A JOURNAL, ENERGY CONVERSION INSTALLATION/FLUID DISTRIBUTION NETWORK INCLUDING SUCH A VALVE AND METHOD OF DEMOUNTING SUCH A VALVE - This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa. | 07-10-2014 |
| 20150075637 | TRAVELING VALVE CAGE - A traveling valve for use with a downhole pump includes a cage shell, which at its lower end, has an integral internal shoulder that defines an axial opening. A retaining ring within the cage shell abuts the internal shoulder. An upper end of a bushing is attachable to a plunger while the lower end of the bushing is attached to the cage shell. The bushing and cage shell define a bore in fluid communication with the axial opening. An insert within the bore allows fluid to flow in the bore from below the insert to above the insert. A ball reciprocates in the bore so as to seat on the retaining ring when the fluid pressure within the bore above the ball exceeds the fluid pressure within below the ball, and to be restrained by the insert when the fluid pressure differential within the bore is reversed. | 03-19-2015 |
| 20160138723 | Isolatable Non-Slam Piston Check Valve - A valve assembly includes a valve body with a central passage, an upstream end for receiving a fluid, and a downstream end for discharging the fluid. A segment ball valve rotates between a valve open position to allow the fluid to flow through the central passage, and a valve closed position to prevent the fluid from flowing through the central passage. A check valve located within the central passage downstream from the segment ball valve is biased to prevent the fluid from traveling upstream through the central passage, and to allow the fluid to travel downstream past the check valve. A locking mechanism secures the check valve in a locked position to prevent the fluid from flowing past the check valve. A sealable cavity is located between the segment ball valve and the check valve, to contain a neutral media to achieve a double block and bleed feature. | 05-19-2016 |
