摘要： A flow control assembly having a body defining a central flow passage and one or more lateral flow openings that facilitate fluid communication between the central flow passage and an exterior of the body, and a flow trim positioned within the central flow passage and defining one or more flow orifices aligned with the lateral flow openings. A flow closure member is positioned within the central flow passage and movable between a closed position, where the lateral flow openings and the flow orifices are occluded to prevent fluid flow through the lateral flow openings, and an open position, where the lateral flow openings and the flow orifices are at least partially exposed to facilitate fluid flow through the lateral flow openings. A sacrificial nose radially interposes the flow closure member and the flow trim to mitigate erosion of the flow closure member.
