The purpose of a blow-off valve in a boiler is primarily to remove sediment and sludge. Over time, as water is heated in the boiler, minerals and impurities can accumulate on the bottom of the boiler or in the water itself. These deposits can hinder the efficiency of the boiler and may lead to potential damage if not managed appropriately.

The blow-off valve is specifically designed to facilitate the removal of these contaminants by allowing water, along with the sediment and sludge, to be expelled from the boiler safely. Regularly using this valve helps maintain optimal performance and prolongs the lifespan of the boiler, as it prevents the buildup of materials that can lead to overheating or corrosion.

While maintaining pressure and managing steam release are crucial aspects of boiler operation, those functions are not what the blow-off valve primarily serves. Adding chemical treatment is also an important part of boiler maintenance, but it is handled through different equipment and processes rather than through a blow-off valve.
