Kesselrohr mit Unterdruckventil von De Dietrich 722268000

The boiler tube with anti-vacuum valve is designed to prevent vacuum formation in the boiler system, which can cause damage or operational issues. This tube incorporates a valve that automatically admits air if negative pressure occurs, protecting the boiler and associated components. It is a safety-critical part for maintaining proper pressure balance during operation and shutdown. Replace your old or faulty tube with this unit to ensure safe and reliable boiler function.
