PURPOSE: A gas valving system is provided to make a variable structure of valving system with no change of the base unit structure. CONSTITUTION: In the gas valving system, at the both side of box of the first, second and third cut off (CB1¯CB3) lie six shutters, each cut off is linearly connected by way of shutter and connection line(12,13). One side of each cut off is connected to the main line(BUS1,BUS2), separated line(14,24) come from the boxes between first and second cut off and between second and third cut off. Bushing of the boxes connected with the front of the separated lines so as to make a unit. The first, second and third cut off of the box are arrayed so that the linking line for the first, second and third actually forms a straight line is between and parallel to the axial line of the main line and the line linking the center of the bushing of each box.
