The traditional process production line has high cost, a single gas pipeline arrangement mode, and a valve body shell is generally designed into a regular shape, so that the requirements of process design are difficult to meet, and the defects of material waste and the like exist.

The traditional gas circuit board is installed on a board, only a gas pipeline is arranged in the board, and a conversion board is required to be installed in the middle during installation, so that the valve body is connected with the gas circuit board.

Therefore, it is desirable to have a light-weight gas circuit board to replace the existing gas circuit board, so as to reduce the occupied space, the system volume and the system cost.
