  • Publication number: 20220010898
    Abstract: A fluid conduit connector includes a monolithic body having a first opening at a first side and a second opening at a second side. A throughbore extends from the first opening to the second opening. A first array of holes in the first side is positioned around the first opening, each hole of the first array of holes terminating within the body. A second array of holes in the first side is positioned around the first array of holes, each hole of the second array of holes extending through the body to the second side.

  • Patent number: 9890609
    Abstract: A safety valve control system may include a remotely operable control assembly, a first transducer, a valve assembly, and a compressor assembly in communication with the control assembly. The control assembly is operable to actuate the pump and valve assemblies to supply fluid to actuate the safety valve into open and closed positions, in response to one or more signals received from the first transducer. A method of operation may include maintaining the safety valve in an open or closed position while sensing a physical property with the control system; communicating a signal corresponding to the sensed physical property to the control system; and automatically closing or opening the safety valve in response to a comparison of the sensed physical property to a pre-set condition.

  • Patent number: 9163750
    Abstract: Embodiments of a method of operating a safety valve and a safety valve system are provided. The valve system includes a valve, an actuator, a mechanical override, and an indicator. The actuator includes a fail-safe mechanism and the indicator is configured to indicate whether the fail-safe mechanism is operable during use of at least one of the actuator and the mechanical override. In one embodiment, a method of operating the safety valve includes actuating the valve into an open position and sending a signal to indicate that the fail-safe mechanism is operable to move the valve to the closed position, while the valve is in the open position.

  • Patent number: 9163619
    Abstract: A valve actuator control system for use with a valve actuator may include two pump assemblies, two control valve assemblies, two transducers, a fluid reservoir, and a controller assembly. The controller assembly may actuate the pump assemblies to direct fluid from the fluid reservoir to the valve actuator, and may actuate the control valve assemblies to direct fluid from the valve actuator to the fluid reservoir. A method of actuating a valve actuator using a valve actuator control system may comprise sending a signal to the valve actuator control system, injecting pressurized fluid from a fluid reservoir of the valve actuator control system into a first chamber of the valve actuator, discharging pressurized fluid from a second chamber of the valve actuator into the fluid reservoir, and actuating the valve actuator from a first position to a second position.

  • Patent number: 9103465
    Abstract: A dual piston valve actuator operable to provide an initial thrust force that is greater than a subsequent thrust force for moving a gate valve from a closed position to an open position. The actuator may include a first piston and a second piston movably disposed within a bore of the first piston. The first piston may define a first piston area for proving the initial thrust force, and the second piston may define a second piston area (that is less than the first piston area) for providing the subsequent thrust force. Movement of the first piston is limited relative to the second piston for moving the gate valve using the initial thrust force an initial portion of the valve stroke, while moving the gate valve using the subsequent thrust force the remaining portion of the valve stroke.

  • Patent number: 9057448
    Abstract: A method and apparatus for a pressure control system for an actuator is provided. In one embodiment, the pressure control system may include a housing defining an upper chamber and a lower chamber, and a piston disposed between the upper and lower chambers. A valve may be coupled to the piston that is operable to control fluid communication between the upper chamber and the lower chamber. In one embodiment, a method of controlling over-pressurization of an actuator includes supplying a fluid pressure to a first chamber of an actuator having a piston and actuating the piston using the fluid pressure. The method may further include relieving the fluid pressure from the first chamber through a valve that is coupled to the piston when the fluid pressure exceeds a predetermined maximum pressure.
