Safety Relief Valves
Pressure Relief Valves are used to control the pressure in a system in case of a process upset, or equipment failure. The extra pressure in the systems is relieved through an auxiliary passage. A typical pressure relief valve is designed to operate at a predetermined set pressure to assist in protecting other vessels and equipment from being subjected to unsafe pressure. If the pressure in the system exceeded the relief valve automatically becomes the passage of least resistance and helps retain the pressure.
