  • Pressure Relief Devices - National Board of Boiler and

    Pressure Relief Devices. Pressure relief devices are used to provide a means of venting excess pressure which could rupture a boiler or pressure vessel. A pressure relief device is the last line of defense for safety. If all other safety devices or operating controls fail, the pressure relief device must be capable of venting excess pressure.Learn More
