Pressure Relief Valve

A pressure relief valve (PRV) is a critical safety device that automatically opens to release excess fluid (liquid or gas) from a pressurized system, preventing damage, equipment failure, or explosions by maintaining pressure within safe limits. It typically uses a spring-loaded mechanism that opens gradually as pressure exceeds a preset point, discharging fluid until pressure drops, then reseals, common in boilers, hydraulic systems, and pipelines.
