Question 1215 Deck General

The correct answer is B) check valve. On a tank vessel, the valve on the discharge side of a cargo pump is typically a check valve. A check valve is a one-way valve that only allows flow in one direction, preventing backflow. This is important on the discharge side of a cargo pump to ensure that the flow of cargo does not reverse direction, which could potentially cause damage to the pump or other equipment. The other options are not as suitable for this application. A butterfly valve is typically used for flow control, a globe valve is better suited for throttling flow, and a gate valve is more commonly used for fully opening or closing a line, rather than preventing backflow.
