Multi-Function Gas Safety Device
The SIMAX 8 safety device is a heavy-duty, multi-function gas safety unit designed to protect tapping points, distribution lines, and gas manifold systems. Manufactured in Germany and compliant with DIN EN ISO 5175-1 and AS 4603, it combines multiple critical safety functions into one robust device for industrial gas applications.
The SIMAX 8 integrates a gas non-return valve, flame arrestor, temperature-sensitive cut-off valve, and dust filter, delivering comprehensive protection against flashback, backflow, overheating, and contamination. Each unit is 100% factory tested for safety and reliability.
Integrated Safety Functions
Gas non-return valve (NV): prevents dangerous gas mixtures
Flame arrestor (FA): stops flashback
Temperature-sensitive cut-off valve (TV): shuts off gas flow if excessive temperature is detected
Dust filter (DF): protects internal components from contamination
