The valve commonly used in pipes larger than 2″ dia is a______________?
Correct answer: D. Gate valve
- A. Globe valve
- B. Plug-cock
- C. Check valve
- D. Gate valve
Explanation
Gate valves provide a relatively unobstructed passage and are economical in large pipe sizes, so they are commonly selected above about 2 inches. Globe valves are better for throttling, while check valves prevent reverse flow.
