Which factor most affects the speed of a pneumatic actuator?

• A. Ambient Color
• B. Air Temperature
• C. Flow Rate To The Actuator
• D. Lubricant Type

Answer: (C)

In pneumatics, how fast a cylinder moves is controlled by how quickly air can fill and push the piston. That rate is the flow rate to the actuator. When the valve and piping allow more air to reach the cylinder, the piston moves faster (assuming the load and pressure permit it). The other options don’t directly set that speed: ambient color has no effect on operation, air temperature can only nudge density slightly and isn’t used to control speed, and lubricant type mainly affects friction and wear rather than the immediate rate air can enter the cylinder. So, flow rate to the actuator is the key factor governing speed.
