The purpose of a boiler blow-off valve is to release excess pressure or remove contaminants from the system. This valve plays a crucial role in ensuring the safe operation of the boiler. Over time, sediment and minerals can accumulate in the boiler water, leading to reduced efficiency and potential damage. By utilizing the blow-off valve, operators can periodically remove this buildup and maintain water quality.

Additionally, if the pressure in the boiler exceeds safe levels, the blow-off valve allows for a controlled release of pressure, which helps prevent potential accidents or failures. This safety feature ensures that the boiler operates within its designated pressure limits and contributes to overall system reliability.

Maintaining the integrity of the water and pressure within the boiler is essential for its performance and safety, making the blow-off valve an important component in boiler operations.
