A500 is a relief / sustaining valve which sustained upstream pressure or relief the high pressure in main pipeline. The P500 relief / sustaining pilot sense the upstream pressure. Under flowing conditions, the pilot reacts to small changes in pressure to control the main valve position by modulating the pressure above the diaphragm. The upstream pressure will be equal to the pilots setting. It released higher pressure in main pipeline or sustain the upstream pressure to make important user always have enough pressure to use.
