  • Patent number: 10724555
    Abstract: A controller configured to improve response time on a valve assembly. The controller may have flow modifying structure that couples with a pair of pneumatic outputs, both pneumatically coupled with an actuator on the valve assembly. The flow modifying structure can be configured to convert incoming instrument air into a pair of independent, pneumatic output signals, at least one of which flows directly to the actuator. In one implementation, a volume booster may be used to increase pressure of the other pneumatic output signal upstream of the actuator.

  • Patent number: 10670054
    Abstract: A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

  • Patent number: 10641668
    Abstract: A safety valve is outfit with sensors to monitor performance. The safety valve may include valve mechanics comprising a closure component moveable relative to a seat. The device may also have a pre-load unit coupled with the closure component. The pre-load unit may utilize a coiled compression spring to generate spring force to keep the closure component in contact with the seat. A strain gauge may be disposed on the compression spring to measure strain, for example, shear strain in the compression spring. Analysis of this data may predict set pressure (or “set point”). This prediction may, in turn, form a basis for an alert or other indicator that the safety valve requires maintenance or repair.

  • Patent number: 10488855
    Abstract: A system that provides localized monitoring of characteristics of instrument gas that a valve assembly uses to modulate the flow of a working fluid. The system includes components that generate an output in response to, for example, particulates, humidity, temperature, and other characteristics of the instrument gas. Processing of data and information in the output can help to diagnose changes in the characteristics of the instrument gas. This diagnosis is useful to predict a time frame during which the valve assembly and components associated therewith might fail and/or require maintenance before the valve assembly manifests significant problem that are detrimental to a process line.

  • Patent number: 10393283
    Abstract: A gap control device that works with a plug on a valve assembly for use in high-temperature applications. The plug may include two parts and a compressible seal that, when compressed, engages with an adjacent wall of a cylinder or “cage” typical of a trim assembly. In one embodiment, the gap control device forms a hard stop that expands in response to high temperatures. This feature prevents excess over-travel between the two parts of the plug in the high-temperature applications so as to limit stress and wear on the compressible seal.

  • Patent number: 10268259
    Abstract: A board-level assembly that is useful to expand functions of a valve positioner on a valve assembly. The board-level assembly can incorporate a main circuit board and a peripheral “smart” circuit board. The main circuit board may be configured to communicate with the smart circuit board, find a storage memory on the second circuit board, retrieve data from the storage memory, and use the data to configure functions on the first circuit board. In one implementation, the smart circuit board can release and engage the main circuit board. This configuration can allow different configurations of the smart circuit board to swap into the board-level assembly, each of the different configurations providing data the main circuit board can exploit to change the functions of the valve positioner.

  • Patent number: 10240621
    Abstract: A valve positioner that can maintain operation of the control valve despite failures in one or more components. The valve positioner may reduce downtime by allowing in-situ repair to occur on the valve positioner. The valve positioner may incorporate a by-pass component, which can utilize control input signals (e.g., a 4-20 mA signal) to energize one or more components (e.g., a current-to-pressure converter) to cause the control valve to modulate fluid flow without the digital microprocessor and/or related components.

  • Patent number: 10234039
    Abstract: Valve assemblies with butterfly valves for use as a double isolation & bleed (DIB) valve and a double block & bleed (DBB) valve. The embodiments may have a twin-disc design with a non-separable, valve body having a central bore. A pair of butterfly valves may reside in the central bore, each having an annular seal and a rotatable disc that contacts the annular seal to prevent flow of fluid into space between the butterfly valves. Implementations of the embodiments configure the annular seal with a sloped contact surface at an angle to positively seal the rotatable discs in the preferred direction of incoming flow. In this way, the valves can always close in response to either uni-directional flow into one end of the central bore or bi-directional flow into both ends of the central bore, respectively or simultaneously.

  • Patent number: 10234057
    Abstract: A method to detect cycling of components that result from use of a tight shut-off mode on a valve assembly. Embodiments of the method use operating data from the valve assembly. This operating data includes data that reflects a position for the closure member relative to the seat. This position often corresponds with a measured position of one or more components (e.g., the valve stem) on the valve assembly. In one embodiment, the method includes steps for comparing the measured position to a boundary criteria that defines one or more boundary values proximate, and often equal to, the threshold levels of the tight shut-off mode. The method can also includes steps for identifying patterns in the data that indicate that the closure member is cycling from its closed position to a second position due to tight shut-off mode.

  • Patent number: 10202987
    Abstract: Embodiments of a directional valve assembly that provides a single device with functionality of a two-position design for automated operation and functionality of a three-position design for manual operation. The embodiments can include a housing with a piston chamber and a spool member that transits in the housing to regulate the flow of a working fluid to a cylinder. The embodiments can also have one or more pilot operators that regulate the flow of pilot air into the piston chamber to move the spool member between two positions, i.e., two open positions. The embodiments can also have a manual operator (e.g., a lever) that can move the spool to the open positions and to a closed position. In one embodiment, the spool member is configured to remain in either a first position, a second position, or a third position in the absence of an outside stimulus on the pilot operators.
