When continuous gas supply is required, it is common to prepare two lines in the gas supply system from separate containers (cylinders) and switch between them alternately during usage. However, in this setup, there is a possibility of temporarily interrupting the gas supply if one of the supply lines runs out of gas.

To address this issue, the 'semi-automatic switching device' is introduced, which automatically switches the gas supply from one line to the other when the gas pressure in one supply system becomes too low.

We offer various types of semi-automatic switching devices based on the gas pressure and required flow rate. For more details, please consult with our company.
