How do pressure safety valves work
WebWhen the pilot valve reaches set pressure it opens and releases the pressure from the dome. The piston is then free to open and the main valve exhausts the system fluid. The … WebA relief valve has a simple disc that rests on the valve seat until pressure builds enough to overcome the spring tension and lift the disc. A safety valve, however, has a lip that the pressure cannot interact with while the valve is closed. When the safety valve cracks, the pressure can reach the lip.
