What is the correct relief valve setting if the working pressure on a Hydro is 400 PSI?

In a hydraulic system, a relief valve is designed to control the maximum pressure within the system to prevent damage to the components. The correct setting for a relief valve should be higher than the normal operating pressure to allow the system to function effectively under normal conditions, while still being low enough to protect the system in case of pressure surges.

Considering that the working pressure is 400 PSI, the relief valve should be set to a level that is above this operating pressure, often by a fixed increment to account for potential hydraulic surges and to ensure that the system remains reliable. Setting the valve too close to the working pressure could lead to it opening too frequently, which is inefficient and potentially harmful.

Setting the relief valve to 600 PSI Max provides a safety margin above the normal working pressure, thus ensuring that it remains functional and protects the system during pressure spikes. This allows the system to handle variations effectively without risking the structural integrity or operational efficiency.

In summary, a relief valve setting of 600 PSI Max is appropriate because it is above the 400 PSI working pressure, offering protection while allowing efficient operation of the hydraulic system.
