Relief Valves are safety devices designed to protect pressurised systems by automatically releasing excess pressure when it exceeds a predetermined limit. Commonly used in industrial fluid and gas systems, these valves help prevent equipment damage, system failure, and potential safety hazards caused by over-pressure conditions.
When system pressure rises above the set pressure, the relief valve opens to discharge the excess fluid or gas, allowing the pressure to return to a safe operating level. Once normal pressure is restored, the valve automatically closes, ensuring the system continues to operate safely and efficiently. This automatic operation provides reliable protection without the need for manual intervention.
