Gas Safety Device – ISO 5175-2
Industrial gas safety device designed for the protection of ring lines, tapping points, and points of use in gas distribution systems. Manufactured in accordance with ISO 5175-2 (NV DF), this device operates without a flame arrestor and is flashback-resistant when compressed air is used as the oxidant.
Engineered for reliable performance with low, position-independent cracking pressure, it is suitable for controlled gas applications where system safety and flow stability are essential.
