An external valve is a control component used in heating systems to regulate flow or pressure. This valve is typically installed outside the main boiler casing, allowing for easy access during maintenance. It can serve various functions, such as isolating sections of the system or draining water. For technicians working on boiler spare parts or burner spare parts, a reliable external valve is essential for efficient system management and repair.
