Foot valves provided in pumps are ____________ valves?
Correct answer: D. Directional control
- A. Relief
- B. Three/four way
- C. Pressure reducing
- D. Directional control
Explanation
A foot valve prevents liquid in the suction line from flowing back when the pump stops, so it acts as a one-way or directional-control valve. It is not a relief or pressure-reducing valve.
