The safety valve or relief valve is a critical safety device in a boiler system designed specifically to prevent excessive pressure build-up. When pressure exceeds a certain threshold, the safety valve opens automatically, allowing steam or hot water to escape. This action helps to relieve stress on the boiler structure and prevents potential catastrophic failures, such as explosions. It serves as a safeguard against overpressure conditions, which could occur due to various operational malfunctions or failures within the system.

In a well-functioning boiler, the safety valve is calibrated to activate at the appropriate pressure limit, ensuring that the system operates safely within its designated parameters. This proactive safety mechanism is vital for maintaining the integrity of the boiler and ensuring the safety of personnel and equipment.
