Abstract: A closure member is configured for use in a valve. These configurations may have a coating or conformal layer that may cover most, if not all, of the underlying material. This layer may include pre-propagated cracks that form due to thermal cycling prior to use in service. These pre-propagated cracks act as stress relief to accommodate for possible thermal stress that occurs due to different rates of thermal expansion between the underlying closure member and the coating. In one implementation, the layer may include a crack profile, which is engineered to direct formation of the pre-propagated cracks as well as to arrest crack development to a certain depth to maintain at least some integral layer of material over the underlying plug 118. This feature can extend service life of the plug, particularly in highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations.

Abstract: A bellows is configured for use on a valve. These configurations may include a corrugated section that is hollow to receive a valve stem therethrough. At its ends, the corrugated section can terminate at adapters. In one implementation, additive manufacturing can construct the bellows as a unitary or monolithic unit, avoiding welds or fasteners that can complicate manufacture of the parts. This techniques can create interfaces between the corrugated section and the adapters that comprises the same material as the adjacent parts.

Abstract: 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 interior and exterior openings. The cage may also have a bore to receive a closure member or “plug.” This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the interior and exterior openings are vertically offset or spaced from another along the axis of the bore. In one implementation, the exterior openings are in a section of the cage that is not normally exposed to flow. This feature can increase density of noise-abating features within given dimensions for the cage (or the valve trim itself). Use of additive manufacturing may be useful (or even necessary) to create these parts within certain design envelopes because these techniques can create the unique flow geometry within a unitary or monolithic body.

The cage may also have a bore to receive a closure member or “plug.” This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the exhausts of flow paths with adjacent inlets are offset or spaced from another. In one implementation, the exterior openings vertically offset. However, other designs may adopt combinations of radial, helical, or angular offsets as well. This feature can prevent mixing of flow from jets that are in the same inlet plane. This feature, in turn, can reduce jet-to-jet interactions that may abate noise.

Abstract: 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.

Abstract: 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).

Abstract: A valve assembly for managing a flow of fluids in hydrocarbon development and production operations includes a valve body having an internal body cavity and a body bore intersecting the body cavity. A valve plug is located within the body cavity and is rotatable between an open position and a closed position. A sleeve is located between the valve plug and the valve body and is rotationally fixed to the valve body and remains rotationally static relative to the valve body as the valve plug rotates. A seal groove is located on a sidewall surface of the sleeve and circumscribes one of the sleeve openings. A seal assembly has a seal ring that is U shaped in cross section with an inner leg that engages the seal groove and an outer leg that extends out of the seal groove and engages one of the valve body and the valve plug.
