Which allows free fluid flow in one direction and no fluid flow in the other direction?

Check valve
Pressure relief valve
Directional control valve
Flow control valve

The correct answer is: Check valve

A check valve is the correct answer because it is designed to only allow fluid to flow in one direction. Option B, the pressure relief valve, is used to release excess pressure in a system and does not control the direction of fluid flow. Option C, the directional control valve, is used to control the direction of fluid flow, but it does not restrict flow in one direction as requested in the question. Option D, the flow control valve, is used to regulate the rate of flow and does not prevent flow in one direction. Therefore, A is the most suitable option for the given question.
