For the same terminal conditions and valve size, the pressure drop in a fully opened globe valve as compared to that in a gate valve is___________________?
Correct answer: A. More
- A. More
- B. Less
- C. Equal
- D. Either A. or B.; depends on the viscosity of the fluid
Explanation
A globe valve forces the fluid through a tortuous, repeatedly changing path, whereas a fully open gate valve offers a comparatively straight passage. Therefore, the globe valve has the greater pressure drop.
