What component is responsible for controlling the pressure in a hydraulic system?

The component that is primarily responsible for controlling the pressure in a hydraulic system is the pressure relief valve. In hydraulic systems, pressure must be maintained within safe limits to prevent damage to components and ensure proper function.

The pressure relief valve plays a crucial role in this by diverting excess fluid back to the reservoir when the pressure reaches a preset level. This function prevents overpressure conditions that could lead to system failure or catastrophic failure of hydraulic components. It helps maintain system stability by regulating the pressure to pre-established limits.

While a hydraulic pump is essential for generating pressure and moving hydraulic fluid through the system, it does not directly control the pressure; it only provides the necessary force. The reservoir holds the hydraulic fluid, and the pressure gauge is used for monitoring pressure levels, but it does not have any active role in pressure control. Therefore, the pressure relief valve is the key component that actively manages pressure within the hydraulic system.
