摘要： A monitor device that is configured for use on flow controls and like industrial devices. The embodiments may include a resonator that is sensitive to vibrations on the flow control. The resonator may generate a non-electrical signal, like pressure waves. This non-electrical signal can transit a conduit to a sensor that can convert the pressure waves into an electrical signal. On valve assemblies, a controller can process the electrical signal to detect potential health or maintenance issues. The controller may, in turn, generate an alert to prompt operators to perform maintenance on the flow control.

摘要： A valve control is configured for use with control valves and other flow controls. The valve control leverages a simplified structure to avoid problems with manufacture and reduce costs. This structure includes a support unit that compresses parts of a valve housing together. Inside of the valve housing, the structure incorporates diaphragms that cause a pair of balanced valves to move in response to changes in pressure of fluid in a conduit. For industrial application, the valve control finds use to maintain pressure of natural gas in pipelines downstream from a control valve.

摘要： A position transfer device is configured for use on a control valve. These configurations may convert a linear position of a closure member on the control valve to an angular position of magnets. A sensor in proximity to the magnets can generate a signal in response to the angular position. A valve positioner or controller can process the signal to identify the position of the closure member relative to a seat. In one implementation, the position transfer device includes a shaft that clamps onto a pin. This arrangement causes the pin to translate radially about an axis that is perpendicular to the shaft. The magnets move in response to the pin.

摘要： A coating that is configured for use on parts of a control valve. The configurations may incorporate various material layers, preferably that form a layered structure on a base or substrate (for example, an Inconel body). 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.

摘要： A pilot-operated pressure relief valve nozzle assembly and associated systems and methods are provided. In an exemplary embodiment, the nozzle assembly includes a body having an elongate shaft with an inner lumen extending therein and a flange at one end of the elongate shaft and having an annular notch formed therein. The annular notch is configured to seat an annular ring, and the annular notch includes an annular groove formed therein that enables communication between a first bore extending through the flange from the inner lumen to the annular groove and a second bore extending through the annular ring, thus allow the first and second bores to be radially offset from one another.

摘要： A method for processing operating data (e.g., position, setpoint, and pressure) for a valve assembly. The method is configured to associate characteristics of operation for the valve assembly with a root cause and/or a contributing factor. In one embodiment, the method can assign a first amplitude with a value that quantifies movement or “jump” of the valve stem that results from stick-slip on the valve assembly. The method can also assign a second amplitude with a value that quantifies a change in the data for the setpoint. The method can further ascertain the relationship or “position” of the first amplitude relative to the second amplitude, or vice versa. The method can use the relationship between the first amplitude and the second amplitude to indicate the root cause of the operation of the valve assembly.

摘要： 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.
