🔍 Key Concepts

• Cargo pump discharge line arrangement on tank vessels • Function of a non-return (one-way) valve in liquid cargo systems • Differences in operation between isolation valves and automatic flow-control valves

💭 Think About

• On the discharge side of a cargo pump, what is the main concern: starting/stopping flow, or preventing backflow and reverse rotation of the pump? • Which valve type from the list is specifically designed to work automatically when flow reverses, without manual operation? • In cargo transfer, which valves are normally used as line or manifold isolation, and which are used primarily as protection for the pump and line?

✅ Before You Answer

• Identify which option is a one-way / non-return valve by design • Eliminate valve types that require manual operation every time flow direction changes • Consider which valve is commonly used to protect pumps from reverse flow and water hammer in cargo systems
