Question

To avoid cavitation the valve should be designed such that

• A. high pressure recovery characteristics with high $F_L$ and $K_c$
• B. high pressure recovery characteristics with low $F_L$ and $K_c$
• C. low pressure recovery characteristics with high $F_L$ and $K_c$
• D. low pressure recovery characteristics with low $F_L$ and $K_c$

Hint:

High pressure recovery valves (like ball or butterfly valves) are highly prone to cavitation because their pressure drops sharply at the narrowest point and recovers rapidly.
Globe valves (low recovery) are much better suited for high pressure-drop applications prone to cavitation.

Answer 1

The Correct Option is C
