Safety
Hydrogen is critical to a wide range of industrial applications, from refineries and chemical processing to fuel cell systems and analytical instrumentation. But the same properties that make it valuable also make it dangerous. Colourless, odourless and burning with a near-invisible flame, a hydrogen leak can go undetected until conditions are already hazardous. With a wide flammability range and an ignition energy roughly 10 times lower than that of most hydrocarbon fuels, the window between a leak and a catastrophic incident is measured in seconds.
Closing that window fast enough and without relying on electricity is where standard shut-off methods may fall short. Left undetected, a hydrogen leak leads to unplanned downtime, damaged equipment and compromised personnel safety that could have been prevented at the source.
For peace of mind, reliability and safety, operators are turning to fully mechanical excess flow valves that provide the rapid, automatic response required to safeguard operations.
