🔍 Key Concepts

• Manual vs. automatic operation of tank valves on tankers • Flow characteristics and typical uses of globe, gate, check, and butterfly valves • Why certain valve types are preferred where low resistance and full-bore flow are needed in cargo systems

💭 Think About

• Think about which valve design gives the least resistance to flow when fully open and is suitable for large-diameter cargo lines on tankers. • Ask yourself which of these valve types is primarily for preventing backflow, rather than for routine open/close control by an operator. • Consider which valve type would be practical to manually operate frequently during cargo loading and discharging, while still giving a clear open/closed position.

✅ Before You Answer

• Identify the primary function of a check valve and see if that matches a manually operated cargo tank valve. • Compare the internal passage when fully open for globe vs. gate vs. butterfly valves— which one is closest to a straight, unobstructed bore? • Consider which valve design is most commonly installed on large tanker cargo lines for manual operation, not small-diameter utility lines.
