Introduction to Pressure Relief Valve
A pressure relief valve is a crucial safety device used in various industrial systems to protect equipment and pipelines from over – pressure situations. When the pressure in a system exceeds a pre – set limit, the pressure relief valve opens to release the excess pressure, preventing potential damage, explosions, or other dangerous incidents. These valves are widely used in industries such as oil and gas, chemical, power generation, and water treatment. Pressure Relief Valve
