What does a meter-in flow control circuit regulate?

What does a meter-in flow control circuit regulate?

• A. Fluid entering the actuator
• B. Fluid leaving the actuator
• C. Back pressure regulation
• D. The color of the actuator

Answer: (A)

The main idea is that this type of circuit controls how much air (fluid) can enter the actuator, which in turn sets the actuator’s speed. By placing a flow control in the supply line to the cylinder, you throttle the inlet air, so the piston extends at a slower, controlled rate. The air exiting the cylinder isn’t restricted by this circuit, which is why retraction can happen faster unless you use a separate meter-out control. It doesn’t regulate back pressure, and the color of the actuator isn’t involved. So the most accurate description is that it regulates the fluid entering the actuator.
