Pressure Relief Valve Application

Tips: What is difference between pressure relief valve and pilot-operated pressure relief valve?

Process pressure exerts an opposing force on the disc. When the process pressure force on the disc overcomes the opposing spring force, the disc lifts and the valve begins to relieve pressure. In contrast, a pilot operated valve uses process pressure to keep the valve closed until set pressure is reached.
