What is the purpose of a safety valve in a boiler system?

The purpose of a safety valve in a boiler system is to relieve excess pressure. This is a critical function that ensures the safe operation of the boiler. When pressure builds up beyond the safe operating limit, the safety valve automatically opens to release steam or water vapor, preventing potential explosions or catastrophic failure of the boiler.

Maintaining proper pressure is essential for safe boiler operation, as excessive pressure can lead to structural failure of the boiler components. The safety valve is calibrated to open at a predefined pressure level, making it an essential safety device designed to protect both the equipment and personnel working around the boiler.

In contrast, other components and mechanisms within the boiler system are responsible for controlling water levels, preventing overheating, and measuring temperature, but none of these functions are the primary purpose of the safety valve. Thus, the safety valve plays a pivotal role in maintaining the integrity of the boiler system through its pressure relief capability.
