The semi-automatic switching device, intended for collecting gas, features two container lines, A and B, each equipped with two regulators connected in parallel.

The device operates by setting a differential pressure on each regulator’s secondary pressure. This setup initiates the gas flow from container line A, which has the higher set value.

As the gas in line A depletes, the device ensures a steady flow and seamlessly transitions to line B, guaranteeing an uninterrupted supply.

It triggers gas flow from line A, selected for its higher pressure setting. As the gas level in line A drops, the device seamlessly switches to line B. This maintains a constant flow rate, ensuring an uninterrupted gas supply.

A buzzer and patrol lamp inform you of the situation, making it convenient for container replacement, thereby enhancing operational efficiency and safety.
