Emergency Relief Valves

In industrial facilities—particularly refineries, petrochemical plants, fuel storage tanks, and process lines—maintaining system pressure within safe limits is critical.
Emergency Relief Valves (Pressure Relief Valves – PRVs) are among the most essential safety components that protect equipment and facilities against overpressure.


Function of Emergency Relief Valves

These valves automatically open when the system pressure exceeds the defined safety limit, allowing excess pressure to be released in a controlled and safe manner.
This prevents potential explosions, equipment deformation, and fire hazards.
Once the pressure returns to normal, the valve closes automatically, ensuring continuous and stable system operation.
