What is a boiler blow down valve?

A boiler blow down valve is part of the boiler blow down process designed to control the amount of solids and sludge that accumulate inside a boiler to ensure proper levels of concentrated solids within the boiler water. When water is boiled and converted to steam concentrations of impurities re left behind and concentrate within the boiler. The solids build up inside the boiler unless the condensate return is 100%. The boiler blow down valve is designed to partially drain the boiler to remove or purge the boiler of excess solids or sludge to maintain the proper water to concentration of solids and to make the boiler perform in a more efficient and economical way.

Each boiler is different and thus affects the amount and frequency for the need for boiler blow down. Global / SFC Valve, offers its years of experience and quality to manufacture boiler blow down valves in accordance with ASME codes for safety and performance of the boiler.
