The vent valve is used to release trapped air from boiler systems, radiators, or piping, ensuring proper water circulation and preventing air locks. Also known as an air vent or bleed valve, it can be manual or automatic. Automatic vent valves expel air without user intervention, maintaining system efficiency. This component is vital for the reliable operation of hydronic heating systems. Replacing a stuck or leaking vent valve restores proper flow and reduces noise in your heating system.
