How often should safety valves or safety relief valves be manually tested?

Manual testing of safety valves or safety relief valves on a monthly basis is crucial for ensuring that these devices function properly when needed. Safety valves are critical components of boilers and pressure vessels, designed to prevent overpressure situations that could lead to dangerous failures. Regular testing helps verify that the valves open at their set pressure and close completely afterward, ensuring their reliability.

Monthly testing aligns with industry best practices and guidelines from various safety organizations, highlighting it as a routine maintenance task that guards against equipment malfunctions. By conducting these tests every month, operators can promptly identify any issues, such as buildup of debris or corrosion, that may affect the valve's operation, thus maintaining the safety and compliance of the system.
