CONTROL VALVE SPECIALIST SERIES — DAY 6 ⚙️🔥

Do you know the real difference between Linear Motion and Rotary Motion control valves?

A Control Valve Specialist must understand not only the valve name, but also how the valve moves, how it controls flow, and where it should be used.

🔹 Linear Motion

• Globe Valve
• Single-Port
• Double-Port
• Cage-Guided
• Angle Valve
• Three-Way
• Four-Way

🔹 Rotary Motion

• Butterfly Valve
• Ball Valve
• V-Ball Valve
• Eccentric Plug Valve
• Rotary Globe Valve

🔹 Special Applications

• Anti-Cavitation Valve
• Low-Noise Valve
• Severe-Service Valve
• Cryogenic Control Valve
• High-Pressure Control Valve

💡 Specialist Rule:
Don’t select a valve just by its name. Understand the process fluid, pressure, temperature, flow characteristic, pressure drop, cavitation, noise, and service conditions before selecting the valve.

Linear or Rotary? Which one would you select—and why? 👇

📌 Save this for your Control Valve interview preparation.
