Natural gas train: what components it includes and what is the correct order

The gas train is the set of components that prepare, control, and secure the natural gas supply before it reaches the burner.

Typical component order

A common arrangement may include a manual valve, filter, pressure regulator, low/high-pressure pressostat, safety solenoid valves, and test points.

Why the order matters

Each component protects or supplies the next one. For example, the filter protects the regulator and valves from impurities.

Test points

Test points before and after key components help identify where a pressure drop occurs.

Conclusion

The gas train is not just a series of valves. It is an organized control and safety system that must have the correct layout and coordination.
