RE-EVALUATING VALVE FIT AND FUNCTION ON A PROCESS LINE
A control system is configured to monitor operation of a flow control, like a control valve. These configurations can use of continuous or real-time data to evaluate fitness or function of the device under operating conditions. This feature can alert operators to problems or issues with one or more devices, or process lines in total. These problems may, for example, indicate that a valve is incorrectly sized for actual working conditions. As a result, engineers may find that the valve is too big (or oversize) or too small (or undersize) because the design process for layout of the process line relies upon a design load that reflects a future maximum (plus some factor of safety), and not the actual working conditions that might prevail once the device is in service in the field.

Integrating fluid pathways into a valve superstructure
A superstructure is configured for use on a flow control, like a control valve. These configurations may have internal plumbing to carry fluid between parts of the valve. In one implementation, the plumbing connects a controller with an actuator to allow a pneumatic signal from the controller to pressurize the actuator. The internal plumbing forgoes the need for external pipes or tubes. This feature can simplify the assembly, as well as reduce the overall package size of the valve to avoid potential fit or interference issues at its location on a process line.

POWERING SENSORS WITH AN EXSITIGN PROCESS CONTROL LOOP
Hardware that is configured to gather data on a process line. These configurations may include devices that can connect to existing process control networks, like 4-20 mA control loops. These devices may include rechargeable power sources, for example, a supercapacitor. This power source can power a sensor or like hardware that resides in proximity to a control valve or other device on the process line. The sensor may require a power level for a short time that significantly exceeds one available from 4-20 mA current loop network. As an added benefit, the circuitry may find use to allow the power source to store power, or re-charge, at periodic intervals to ensure that the sensor can gather data regularly during the lifetime of the control valve.
A recovery unit configured to re-inject lost or fugitive emissions back into a pipeline. These configuration may include a pressure vessel that can hold gas (or other fluid) that might vent to atmosphere from, for example, a valve or like flow control. A pump may couple with the pressure vessel. In use, this pump can draw fluid out of the pressure vessel and pressurize it to inject back into the pipeline, typically downstream of the valve. The pump may utilize upstream pressure as a power source.
A control system is configured to monitor operation of a flow control, like a control valve. These configurations can use of continuous or real-time data to evaluate fitness or function of the device under operating conditions. This feature can alert operators to problems or issues with one or more devices, or process lines in total. These problems may, for example, indicate that a valve is incorrectly sized for actual working conditions. As a result, engineers may find that the valve is too big (or oversize) or too small (or undersize) because the design process for layout of the process line relies upon a design load that reflects a future maximum (plus some factor of safety), and not the actual working conditions that might prevail once the device is in service in the field.

An evacuation unit is configured to remove entrapped fluid from a flow control. These configurations may incorporate devices that can passively discharge fluid in response to loss of system pressure. These devices may use gravity or spring-assist as mechanisms to move fluid out of spaces in the device. This feature mitigates risks that the entrapped fluid freezes and expands, which can cause damage to metal components and lead to extensive downtime of process lines. As an added benefit, the features can reduce product costs or complexity because the proposed designs avoid the need for additional, peripheral “accessories,” like pumps or heating elements, resident at the location of the flow control.

A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has a spiral design or layout. This flow path can direct flow around a central bore. A plug may reside in this bore. This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the spiral design can split flow inside of the cage. This feature can elongate travel of flow without any increase in dimensions of the cage (or the valve trim itself). Use of additive manufacturing can further maintain these parts within certain design envelopes because these techniques create the unique flow geometry within a unitary or monolithic body. In this way, the valve trim of the present disclosure can maintain, or even reduce, costs of the control valve, while at the same time it can simply the overall construction of the valve device.

A valve housing is configured to maintain temperature of a valve. These configurations may incorporate paths or channels in structure of the valve that carry working fluid. Heating fluid, like steam or hot water, may flow through these paths to heat this structure. This feature can maintain or raise temperature of the working fluid to meet specifications, standards, or process parameters. In one implementation, the paths may have complex routes or geometry with curves, bends, or other feature that can maximize surface area that is available to distribute heat to the device. This geometry may require manufacturing techniques, like additive manufacturing, that can generate unitary or monolithic structures, particularly those structures that includes voids in the material to form the integral paths for the heating fluid.
A valve bonnet defines a packing box having an inner surface Roughness Average (Ra) of 0.15 or less, for example, between 0.10 and 0.15. Multiple Polytetrafluoroethylene (PTFE) packing rings are in a packing stack. A packer is bolted to the bonnet and extends into the packing box. The packer is configured to apply a packing pressure on the packing, for example, between 100 megapascals (MPa) and 200 MPa. Such arrangements can allow for high pressure valves, for example valves that can retain up to 10,000 pounds per square inch (PSI) of pressure or up to 15,000 PSI.

A sensor configured to measure rate of flow of fugitive emissions on a flow control. The configurations may include devices that are sensitive to low flow or low pressure. These devices may include piezo-electric films or foams. These materials may deflect in response to flow of fluid along the outer surface of the reciprocating shaft. In one implementation, the embodiments can generate average leak rate over time and measure against regulation or specifications to ensure appropriate operation (e.g., leak suppression) of the flow control. Storing this data can provide a database of information that allows operators to benchmark performance of the flow control, for example, to correlate leaks to a certain date or time. This feature may, in turn, permit the operators to also correlate the device-specific performance to overall plant or network operations.

In one implementation, the layered structure can be arranged as "stacked" individual layers that exhibit different concentrations or ratios of materials, including by example tungsten carbide and nickel alloy. The concentration of tungsten carbide may increase from an innermost layer to an outer most layer. This feature can extend service life of the parts, particularly when in use with highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations. Manufacture of the layered structure on the parts may require use of additive manufacturing technology in order to deposit layers of material of varying composition and thickness on the unique fluted design contemplated herein.

A locking mechanism (122) is configured to secure a seat (120) on a valve (108). The configurations may include a pin (124) with a tapered end (128). The pin (124) extends into the valve body (110) to engage with an engagement feature (194), like a slot, on the seat. The slot (192) may reside on the downstream side of the seat (120). This location can provide ready access to the pin (124), for example, through various features found on the valve body (110), such as a boss (178). For steam conditioning valves, the locking mechanism (122) may prove useful because it allows the seat (120) to easily remove from the valve body (110).

A safety system is configured to remotely shut off flow of material through a safety shut- off device. These configurations may include a solenoid valve that couples with an actuator on the shut-off device. In use, the solenoid valve may change state in response to an outside stimuli, like a signal from an operator's central monitoring station. This change in state may cause the actuator to operate, for example, by actuating a latch. The latch may move a flapper in the shut- off device to cease flow of material. In the field, the safety system may find use in pipe and pipeline networks that carry natural gas, wherein remote shut-off of this type can offer rapid, real- time response to problems (e.g., wildfires) in proximity to the networks.

A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.

A pilot assembly is configured for use with various types of flow controls. These configurations include a manifold with an internal flow network that connects pilot valves and an adjustable orifice. The pilot valves may have a fixed and variable differential pressure. In one implementation, the manifold comprises a pair of separable blocks, one each that includes part of the internal flow network. This construction also permits the manifold to expand with, for example, and additional block for an additional pilot valve. This feature configures the manifold for use in working monitor systems or those systems that deploy multi-stage pressure regulation.
