    When the second turbine generator was started, this valve was opened to allow for steam at 600 psi and 850 degrees to pass. As this valve got hot, the nuts were expanding at a much greater rate than the bolts, and they lost the strength to contain the steam's force under the bonnet.

  • Relief Valves - an overview | ScienceDirect Topics

    Perhaps no one valve plays as critical a role in the prevention of industrial accidents as the pressure relief valve. This "silent sentinel" of industry, sometimes referred to as the "safety" or "safety relief" valve, is essential in helping us minimize industrial accidents caused by the overpressurization of boilers and pressure vessels [20] .

    2009/5/5 · The safety valve will close once the system pressure reduces to what is called the "reseat pressure.". The valve will have to be set in such a way that the reseat pressure is 95% of the set pressure. The percentage of this is called the "percentage blowdown" and is limited to a maximum of 5% to avoid wastage of steam produced.
