🔍 Key Concepts

• Identify the type of valve shown (look at the disk in the flow path and the flat lever on top). • Think about how lever-operated valves normally move between fully open and fully closed positions. • Compare valves that need multiple full turns of a handwheel versus valves that work with a single short movement of a lever.

💭 Think About

• From the picture, how far would the lever need to move to rotate the disk from fully closed (across the flow) to fully open (in line with the flow)? • Which answer choices describe many turns of motion, and which describe a single, quick motion? • Does the illustration show a round handwheel for many turns, or a notched quadrant that suggests a limited range of lever travel?

✅ Before You Answer

• Make sure you recognize that this is a butterfly-style valve with a flat disk in the line. • Confirm whether the lever appears designed to move through about 90 degrees (one-quarter turn) or to spin around many times. • Eliminate any choice that mentions one or more complete turns of the lever, since the pictured lever cannot rotate continuously.
