When backflow is not an option: True tightness without compromise

In many industrial applications, simple check valves are used. They are cost-effective, robust, and usually reliable – but not always completely tight. Especially with gaseous media, low system pressure, or in GMP-critical processes, they often do not meet the necessary requirements. Even minor leaks can have serious consequences: from cross-contamination and quality loss to system downtime.

Our high-quality backflow prevention valves offer a reliable, permanently tight solution for demanding applications. They are used wherever backflow must be physically prevented – regardless of the medium, pressure, or environment.
