When choosing among valves, which valve exhibits the largest pressure drop?

The globe valve is known for its significant pressure drop compared to other valve types due to its design. Its internal construction features a globe-shaped body that creates a tortuous path for the fluid to flow. This results in increased friction and resistance against the flow, leading to a greater pressure drop as fluid navigates through the valve.

In this design, the flow path changes direction, which further contributes to turbulence and energy loss, amplifying the pressure drop. While ball, gate, and check valves typically allow for more streamlined flow, resulting in lower pressure drops, the globe valve's configuration facilitates a higher resistance, making it less suitable for applications where minimizing pressure drop is critical.

Thus, in applications where pressure drop is a concern, the choice of valve type is crucial, and the globe valve would be less favored compared to the others mentioned in the choices for its propensity to create a substantial pressure drop.
