Question 1305 Deck General

The correct answer is C) check valve. On a tank vessel, a check valve is typically installed on the discharge side of a cargo pump. This is because a check valve allows fluid to flow in only one direction, preventing backflow from the cargo tank or piping system back into the pump. This is an important safety and operational feature to protect the cargo pump from damage or pressure surges. The other options (globe, butterfly, and gate valves) do not provide the same one-way flow control functionality that is required on the discharge side of a cargo pump.
