A Pressure Relief Valve (PRV) is a safety device designed to control or limit the pressure in a system. It automatically opens to release excess pressure when it exceeds a predetermined level, preventing potential damage or failure of equipment. PRVs are commonly used in various industries, including oil and gas, chemical processing, and water treatment. These valves are crucial for maintaining safe operating conditions. By releasing pressure, they help protect pipelines, tanks, and other equipment from overpressure situations. Regular maintenance and testing of PRVs ensure they function correctly and provide reliable protection against pressure-related hazards.
