The valve used for very remote and accurate control of fluid is a _____________ valve?
Correct answer: D. Needle
- A. Butterfly
- B. Globe
- C. Gate
- D. Needle
Explanation
A needle valve has a tapered stem and small passage, allowing fine adjustment of flow even at low rates. Gate and butterfly valves are mainly isolation valves, while globe valves provide regulation but are less fine for very small flows.
