Gain Insight into the Boiler Valve Applications,
Operational & Performance Characteristics of Pressure Relief Valves
On a boiler, the pressure relief valve is one of the most important safety aspects. It is used to ensure that the build-up of intensive pressure within the boiler can be relieved in order to avoid catastrophic accidents. It works as an open-close feature: opening when the pressure has built up to dangerous levels and closing once normal pressure levels have been reached. For a boiler to function effectively and to the best of its ability, it is important that the pressure relief valves are rightly sized, selected and maintained on a regular basis.

Emerson’s proven, reliable PRV solutions combine unparallel technical expertise with deep application knowledge for the best power plant protection.
