Temperature Considerations for Pressure Relief Valve Application - National Board of Boiler and Pressure …
A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. This valve would have a stamped set pressure of 500 psig and a CDTP of

Safety Valve Capacities in High Pressure Steam Systems
The safety valve must as minimum have the evacuation capacity of all the vapor the boiler can produce running at full power at the working (or certification) pressure. for a higher pressure the steam is compressed and requires less volume and the size of the valve can be reduced. for a lower pressure the steam is expanded and requires more

2021/10/14 · Boiler relief valves serve the same purpose – automatically lowering boiler pressure – but they function a bit differently than safety valves. A relief valve doesn't open fully when pressure exceeds a defined threshold; instead, it opens gradually when the pressure threshold is exceeded and closes gradually until the lower, safe threshold is reached.
