At what pressure does the relief valve blow on a high-pressure machine?

The relief valve on a high-pressure machine is designed to activate and release excess pressure to prevent system failure or damage, maintaining safe operational parameters. The correct pressure at which this relief valve blows can vary depending on the specifications of the specific machine or system being discussed. In many high-pressure applications, a standard relief valve may be set to open at 300 psi to protect the integrity of the equipment. This level is commonly utilized because it provides an appropriate safety margin to avoid catastrophic failures while ensuring the system operates efficiently under normal conditions. The choice of 300 psi indicates a balance between operational efficiency and safety, aligning with industry practices and standards.
