🔍 Key Concepts

• Proper valve seating to prevent leakage and damage • Difference between hand-tight, wrench-tight, and using mechanical stops/locks • Risk of over-tightening valves and damaging the valve seat or stem

💭 Think About

• Which option best prevents both leakage AND damage to the valve over time? • Is relying on maximum force (hand or wrench) always the safest way to close a valve? Why or why not? • What role do built-in mechanical features (like stops or locks) play in ensuring the valve is correctly seated?

✅ Before You Answer

• Consider which method avoids over-tightening that could damage the valve seat • Think about how you would ensure a repeatable, correct closed position for different operators • Ask: which choice matches standard good practice in engineering and tank ship operations, not just "tightening as much as possible"?
