If an actuator requires 72 lpm at 112 bar, what is the effect of increasing the size of the proportional valve?

Increasing the size of the proportional valve in a hydraulic system can indeed affect how the system operates, particularly in terms of response time. A larger valve can allow for increased flow rates, potentially leading to a more responsive system when it comes to actuator movement. However, it may also introduce delays due to more mass that has to be moved and larger fluid volumes that must be controlled compared to a perfectly sized valve.

In this context, opting for a valve that matches the actuator’s flow requirements too closely can lead to better control and reduced delay. Therefore, a valve that is too large may cause a lower system response time, as it may become less sensitive to small control signals, given it allows much more fluid to pass through than necessary.

In terms of energy usage, a properly sized valve for the specified flow and pressure should maintain efficiency without unnecessary energy consumption spikes. Thus, while the choice suggests there will be no effect on energy consumption, it points to the core idea that system adjustments need to be made intentionally to maintain efficiency while optimizing performance.

Overall, with an oversized valve, the system's response time might indeed decrease due to slower reaction to control inputs, aligning with the principles of hydraulic control. Hence, while it may consume an appropriate amount of
