In hydrogen applications, every second matters – especially when it comes to safety shut-off processes. Our safety shut-off dampers comply with the EN 161 standard and close in less than one second (Class A). This ensures rapid response in critical situations and provides reliable protection for both personnel and equipment.

What does EN 161 mean?

EN 161 is a European standard defining strict requirements for automatic shut-off valves regarding safety, performance, and design. For demanding industrial applications, this includes:

• Design according to the highest safety classification, Class A, with a response time of less than one second
• Testing and certification as a fully type-tested unit, including valve and pneumatic actuator
• Reliable shut-off performance and high operational safety under challenging conditions

Why is this certification essential for hydrogen applications?

Hydrogen is a highly sensitive medium due to its volatility and flammability. In the event of a malfunction, a fast and dependable shut-off process is crucial.

EN 161 certification provides:

• Reduced response times within the system
• Enhanced protection for personnel, equipment, and processes
• Compliance with important industrial safety and operational standards for hydrogen applications
• Increased operational reliability and minimized downtime risks

This creates a dependable safety solution for modern hydrogen systems and applications.
