🔍 Key Concepts

• Centrifugal cargo pump characteristics – what happens to flow when the pump stops • Backflow prevention in piping systems on tank vessels • Differences in function between a check valve, gate valve, butterfly valve, and globe valve

💭 Think About

• When a centrifugal pump stops, what would cause oil to run back toward the tanks, and what basic valve function is needed to stop that? • Which of the listed valves can operate automatically with flow direction (without manual operation)? • Which valve types are mainly used for throttling or full open/close control, rather than for one‑way flow protection?

✅ Before You Answer

• Identify which option is specifically designed to allow flow in only one direction • Eliminate any valves that require manual operation to stop reverse flow • Think about which valve type you would expect to see installed immediately downstream of a pump to protect against reverse flow or reverse rotation
