🔍 Key Concepts

• Gate vs. globe vs. needle valves – how each is designed to control flow • Throttling (partially open) vs. fully open/closed service and what damage can occur • Where erosion or vibration can occur if the wrong valve is left partially open

💭 Think About

• Think about which valve type is best suited for ON/OFF service rather than fine flow control. • Which valve design would suffer damage or excessive wear if it is left in a partly open position for long periods? • Which valve types are commonly used for regulating or throttling flow, rather than just isolating (shutting off) a line?

✅ Before You Answer

• Identify which valve has a sliding gate or wedge that should be either fully out of the flow or fully blocking it. • Identify which valves are specifically designed for flow regulation (fine control) and can safely operate partially open. • Eliminate any valve that is normally used for throttling or automatic, one-way flow rather than simple open/closed isolation.
