Which type of valve creates much less pressure drop compared to a globe valve?

The gate valve is designed to provide minimal resistance to fluid flow when it is fully open, which results in a significantly lower pressure drop compared to a globe valve. This is primarily due to its design, which features a flat sliding gate that allows fluid to flow straight through. In contrast, globe valves are intended for regulation and throttling of flow, leading to higher resistance due to the changes in direction the flow must navigate, inherently resulting in a greater pressure drop.

By allowing for nearly full flow capacity when opened completely, the gate valve is best utilized in applications where the flow needs to be either fully on or fully off, rather than controlled in between, further enhancing its performance in high-flow scenarios with less pressure loss.
