← TechnologyWhich malfunction occurs when improperly sized pneumatic control valve rapidly closes during high flow?
A)Valve stem buckling from thermal stress
B)Pressure surge (water hammer) in piping✓
C)Actuator failure from exceeding torque limits
D)Cavitation erosion from local vacuum creation
💡 Explanation
When a valve rapidly closes during high flow, the momentum of the fluid is suddenly stopped inducing a pressure surge (water hammer) because the kinetic energy is converted into pressure. Therefore, a pressure surge results rather than buckling, actuator, or cavitation which require different failure modes.
