A valve that provides linear motion during operation is called

• A. Butterfly valve
• B. Gate valve
• C. Ball valve
• D. All of the above

Answer: (B)

Understanding motion in valves helps you pick the right type. Linear motion means the closing component moves straight along the flow path, up and down, without rotating. A gate valve does exactly that: its stem raises and lowers a gate to open or close the passage, converting input into straight-line movement. In contrast, butterfly valves rotate a disc around a shaft to open or close, and ball valves rotate a ball with a bore to achieve closure. Those are rotary, quarter-turn devices. So, the valve that provides linear motion during operation is the gate valve.
