Question 2825 Deck General

The correct answer is C) Gate valve. Gate valves provide the least resistance to fluid flow when fully open compared to the other valve types listed. This is because gate valves have a straight-through flow path with minimal obstructions when open, allowing for unimpeded fluid passage. In contrast, butterfly valves have a disc that partially obstructs the flow, globe valves have a flow path that is more convoluted, and packless valves may have some additional internal components that can create more resistance. The straight, unobstructed flow path of a fully open gate valve makes it the most efficient option for MODU piping systems where minimizing pressure drop and flow resistance is important.
