the pressure relief valve, therefore, is the process fluid. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure relief valve may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that. Pressure relief valves and their operation. There are two types of pressure relief valves: spring-loaded pressure relief valves and pilot operated pressure relief valves. In a spring-loaded pressure relief valve, the closing force is generated by a helical spring. The set pressure is adjusted by pretensioning this spring with the adjusting screw.
