A product pipeline is a system that transports liquid or gas products from one location to another. A control valve is a device that regulates the flow of the product through the pipeline, by adjusting its position or opening. A control valve should be selected based on the characteristics of the product, the operating conditions, and the performance requirements of the pipeline system. A coating fluid is a type of product that forms a thin layer or film on the surface of the pipeline, which can affect the flow and pressure of the product. A coating fluid can cause some residual buildup, which is the accumulation of solid or semi-solid material in the pipeline, which can reduce the flow capacity, increase the pressure drop, and damage the pipeline or equipment. For a product pipeline 49 miles in length, with a coating fluid that causes some residual buildup, which control valve would you select?
