A meter-out flow control circuit is used to control loads in which of the following ways?

• A. Aiding loads
• B. Builds back pressure at the actuator
• C. Opposing loads
• D. All of the above

Answer: (D)

Meter-out flow control works by throttling the fluid as it leaves the actuator, so it directly sets the speed of motion in the direction where the fluid exits the cylinder. That throttling creates back pressure in the actuator, which can slow or even hold a load to give a smooth, controlled movement and to cushion stops. Because the same restriction affects how the load behaves in different directions and with different loads, the circuit can be used to oppose motion (slow a fast push or pull), to slow and hold a load, or to help the load move more smoothly when other forces are assisting it. In other words, a meter-out arrangement can be used to aid, to build back pressure, and to oppose loads, so all of these outcomes are achievable.
