Which component in a hydraulic system controls the maximum pressure?

The pressure limiting compensator is specifically designed to regulate and control the maximum pressure within a hydraulic system. It ensures that the system operates safely and efficiently by preventing excessive pressure buildup that could lead to equipment failure or damage. When the pressure reaches a predetermined threshold, the pressure limiting compensator will divert flow or relieve pressure, maintaining the system within its safe operational limits.

In contrast, a flow control valve primarily regulates the flow rate of hydraulic fluid, allowing for adjustments to the speed of actuators, but it does not limit the pressure. A check valve prevents backflow in the system but does not control pressure levels. A pneumatic regulator, while it helps control pressure, is used in pneumatic systems, not hydraulic systems, making it irrelevant for this context. Understanding the specific role of each component is crucial for effective hydraulic system management.
