The function of overflow valves (relief valves, pressure retaining valves) is, that the outflow of the medium at a set pressure, in which an existing back pressure or vacuum having no effect on the set over pressure (retaining pressure). The above listed items are characteristic for an upstream pressure regulator, by comparison to a normal safety valve. The safety valve is only a device to prevent a specific pressure from being exceeded (set pressure).
